Question

A rectangle with area 88 has width 11. What is the numerical value of the perimeter?

Answer 1

Answer: Perimeter = 38

=============================================

Work Shown:

A = area of rectangle = 88

W = width = 11

L = unknown length

A = L*W

88 = L*11

11L = 88

L = 88/11 ... divide both sides by 11

L = 8

The length is 8

----------

P = perimeter of rectangle

P = 2L+2W

P = 2(L+W)

P = 2(8+11)

P = 2(19)

P = 38
