How do you do a perimeter?

Example 1: . Find the perimeter of a triangle with sides measuring 5 centimeters, 9 centimeters and 11 centimeters. . Solution: . P = 5 cm + 9 cm + 11 cm = 25 cm … . Example 2: . A rectangle has a length of 8 centimeters and a width of 3 centimeters. Find the perimeter. . Solution 1: . P = 8 cm + 8cm + 3 cm + 3 cm = 22 cm . Solution 2: . P = 2(8 cm) + 2(3 cm) = 16 cm + 6 cm = 22 cm . In Example 2, the second solution is more commonly used. In fact, in mathematics, we commonly use the following formula for perimeter of a rectangle: , where is the perimeter, is the length and is the width. . In the next few examples, we will find the perimeter of other polygons. . Example 3: . Find the perimeter of a square with each side measuring 2 inches. . Solution: . = 2 in + 2 in + 2 in + 2 in = 8 in . Example 4: . Find the perimeter of an equilateral triangle with each side measuring 4 centimeters. . Solution: . = 4 cm + 4 cm + 4 cm = 12 cm . A square and an equilateral triangle are both examples of regular polygons . Another method for finding the perimeter of a regular polygon is to multiply the number of sides by the length of one side. Let's revisit Examples 3 and 4 using this second method. . Example 3: . Find the perimeter of a square with each side measuring 2 inches. . Solution: . This regular polygon has 4 sides, each with a length of 2 inches. Thus we get: . = 4(2 in) = 8 in . Example 4: . Find the perimeter of an equilateral triangle with each side measuring 4 centimeters. . Solution: . This regular polygon has 3 sides, each with a length of 4 centimeters. Thus we get: . = 3(4 cm) = 12 cm . Example 5: . Find the perimeter of a regular pentagon with each side measuring 3 inches. . Solution: . = 5(3 in) = 15 in . Example 6: . The perimeter of a regular hexagon is 18 centimeters. How long is one side? . Solution: . = 18 cm . Let represent the length of one side. A regular hexagon has 6 sides, so we can divide the perimeter by 6 to get the length of one side (). . = 18 cm Ã· 6 . = 3 cm . Summary: . To find the perimeter of a polygon, take the sum of the length of each side. The formula for perimeter of a rectangle is: . To find the perimeter of a regular polygon, multiply the number of sides by the length of one side. . (MORE)
