In one sentence, describe what the following article is about: Perimeter is the outside boundary around a closed geometric figure, and different shapes will require different approaches. If the shape that you want to find the perimeter of is not a closed shape, the perimeter cannot be taken. If this is the first time you are calculating perimeter, try a rectangle or a square. These regular shapes will make finding the perimeter easier. You will use this rectangle as a practice shape and will find its perimeter. Make sure that the opposite sides of your rectangle are the same length. You can do this with a ruler, measuring tape, or by making up your own example. Write down this number by the side it represents so you don't forget its length. As a guided example, imagine that the length of one side of your rectangle is 3 feet.  For small shapes you may want to use centimeters or inches, while feet, meters or miles will work better for larger perimeters. Since the opposite sides of rectangles are equal, you will only have to measure one of each set of opposing sides. You can measure the width with a ruler, measuring tape, or by creating your own example. Write down the value for your width next to the horizontal side of your rectangle it represents. Continuing with the guided example, imagine that in addition to a length of 3 feet, that the width of your rectangle is 5 feet. Rectangles have four sides, but the length of opposite sides will be the same. This is also true for your rectangle's width. Add the length and width used in the guided example (3 feet and 5 feet respectively) to the opposite sides of your rectangle. One a piece of scratch paper, or on the paper you have written the guided example, write: length + length + width + width.  So, for the guided example, you would add 3 + 3 + 5 + 5 to get a perimeter of 16 feet (4.9 m).  You can also use the formula 2(length + width) for rectangles, since the length and width values are doubled. In our example you would multiply 2 by 8 to get 16 feet (4.9 m). Unfortunately, different shapes will require different formula for you to solve for perimeter. In real life examples, you can measure the outside boundary of any closed geometric shape to find its perimeter measurement. But you can also use the following formulas to find the perimeters of other common shapes:  Square: length of any side x 4 Triangle: side 1 + side 2 + side 3 Irregular polygon: add all sides Circle: 2 x π x radius OR π x diameter. The π symbol stands for Pi (pronounced like pie). If you have a π key on your calculator, you can use it to be more accurate when using this formula. If not, you can approximate the value of π as 3.14.  The term "radius" refers to the distance between the center of a circle and its outside boundary (perimeter), while "diameter" refers to the length between any two opposite points on the perimeter of a circle that pass through the circle's center.
Summary: Determine the shape you want to measure. Draw a rectangle on a piece of paper. Find the length of one side of your rectangle. Find the width of one side of your rectangle. Write down the correct measurements on the opposing sides of your rectangle. Add all your sides together. Adjust your approach for different shapes.

In one sentence, describe what the following article is about: A basic fabric store should carry all the required items. Many fabric stores will offer left over scraps of fabric at discount prices. You will need a swatch that measures at least 20 inches (50.8 cm) by 3 inches (7.6 cm). Soft, pliable elastic will work better than thick, rigid elastic. You want the strap to have some give to it.
Summary: Begin by collecting all of the necessary items that are needed to complete your clip. Consider what fabric you would like to use to make the strap. Locate a roll of 1-inch wide elastic. Look for a roll of non-sticky Velcro or a package of small pieces of non-stick Velcro that can be cut to fit your strap. Pick up a suspender clip with a loop measuring 1-inch wide. Shop for a decorative embroidered patch that is not much larger than ½ inch by ½ inch.

In one sentence, describe what the following article is about: You can skip straight to the next step to find which country it is made in, but this basic information is easy to check and remember.  If the first character is an A, B, C, D, E, F, G, or H, the vehicle was made in Africa.  J, K, L, M, N, P, or R as the first character means the vehicle was made in Asia. This includes the Middle East. Note that a VIN never begins with a zero or O due to the ease of confusing these two symbols.  S, T, U, V, W, X, Y, or Z indicate Europe.  1, 2, 3, 4, or 5 indicate North America, including USA, Mexico, and Canada.  6 or 7 indicate Australia or New Zealand. Note that nearby nations such as Indonesia or the Philippines are considered part of Asia for this purpose.  8 or 9 indicate South America. Many vehicles are made in a different country than the one the manufacturing company is located in. Compare the first two characters of the VIN to an online chart like this one, including the first "continent" code described above, and find out where a vehicle was really made. This will also tell you which company made the car. Some companies use the third digit as well to indicate manufacturer or company division. The first two digits should be enough to identify the country and company, however. This method will always work for North American cars, and will often work for cars from other regions. Note that this might be one year later than the car was actually made. A model year of 2008 means the car was probably made either in 2007 or 2008. See below for decoding instructions:  A 10th character which is an A, B, C, D, E, F, G, or H indicate the years 1980 – 1987 in alphabetical order, or the years 2010 – 2017. J, K, L, M, and N are reserved for model years 1988 – 1992, or 2018 – 2022. P means the model year is 1993 or 2023. R, S, and T mean 1994 – 1996 or 2024 – 2026. V, W, X, and Y mean 1997 – 2000 or 2027 – 2030. 1, 2, 3, 4, 5, 6, 7, 8, and 9 indicate the years 2001 – 2009 or 2031 – 2039. A real VIN never contains the letters I, O, or Q. The year code has additional restrictions, never using the number 0 or the letters U or Z. If you're not sure whether your car is new or old, check the vehicle's 7th character. If this is a number, your vehicle's model year is earlier than 2010. If the 7th character is a letter, the model year is 2010 or later (until 2039).
Summary:
Use the first character to discover the continent of manufacture. Use the first two characters to narrow it down to country and manufacturer. Use the tenth character to determine the model year.
