The distance around or Perimeter of a Rectangle is equal to the sum of the length of the 4 sides.
18' + 40' + 18' + 40' = 116'
Perimeter is 40 feet.
40 feet
40 feet
The perimeter is exactly one mile (5,280 feet).
One mile (5,280 feet).
5280 feet approximately, got the info off the net.
10 x 4 sides = 40 feet
8 by 12
It is: 12+8+12+8 = 40 feet
12 feet
Assume 160 lineat feet is a perimeter of a square. Then the square side equals 160/4 = 40 feet Then the area equals 40 x 40 = 1600 sq ft.
If your object is 11.3 feet by 8.7 feet then I have it on good authority that it is not square! It is a rectangle and we find the perimeter by adding the length to the width and then doubling the result. Perimeter = 2(11.3 + 8.7) = 2 * 20 = 40 feet.
