Question

The width of a rectangle is seven meters less than the length. The perimeter is 58 meters. Find the length and width.

Answer 1

Length = x
Width = x - 7
Perimeter = 2* length + 2* width
58 = 2x + 2(x - 7)
58 = 2x + 2x - 14
4x = 58 + 14
4x = 72
x = 18

Length = 18 inches
Width = 11 inches.

Hope this helps.
