Question

The perimeter of a rectangle is 32centimeters. The width is 7 centimeters.

Answer 1

Answer:

63 sq-cm

Step-by-step explanation:

Perimeter = length + width + length + width = 2L + 2W

Area = length * width = LW

Given:

W=7

P=32

Substitute values for P and W into first equation:

32 = 2L + 2(7)

32 = 2L + 14

18 = 2L

9 = L

What is A?

A = LW

A = (9)(7)

A = 63 sq-cm
