If one side is 8 m then the side opposite is also 8 m. Similarly if the adjacent side is 3 m then the side opposite that is also 3 m. thus the perimeter = 8+3+8+3 m = 22m.
perimeter is the sum of all sides. 3+3+8+8 = 22 feet
The perimeter of a rectangle can be calculated by adding up the lengths of all its sides. In this case, the rectangle is 7 inches by 8 inches, so its perimeter would be 2(7) + 2(8) = 14 + 16 = 30 inches.
Perimeter = 12 + 12 + 8 + 8 = 40.
Perimeter = (length+breadth) times 2 = (3 + 3/8) x 2 = 66/8 = 63/4
