Question

Given the perimeter of a rectangle and either the length or​ width, find the unknown measurement using the appropriate formula.

The perimeter is 70ft . and the width is 16ft .

Answer 1

Explanation:

Givens

P = 2*L + 2*W

P = 70

w = 16

Solution

70 = 2L + 2*16

70 = 2L + 32

70-32 = 2L

38 = 2L

38/2 = 2L/2

L = 19
