Question

The length of a rectangle is four times its width. If the perimeter of the rectangle is 80m , find its length and width.

Answer 1

Width = 8 m

Length = 32 m

Explanation:

Width = w

Length = 4w

Perimeter = 80 m

2*(length +width) = 80

2 *(4w +w ) = 80

2* 5w = 80

10w = 80

w = 80/10

w = 8 m

Width = 8 m

Length = 4 * 8 = 32 m
