Question

The length of a rectangle is five times its width.

If the perimeter of the rectangle is 84 m, find its length and width.

Answer 1

Answer:let

Length =L

Width =W

L=5W

Perimeter(p)=2L+2W

P=10W+2W

84=12W

Divide both sides by 12

W=7m

L=5*7=35m

Hence, the length and width are 35m and 7m respectively
