Question

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

The perimeter is 44 in, and the length is 14 in.
The width of the rectangle is
in

Answer 1

The width of the rectangle is 8in

Explanation:

Given parameters:

Perimeter = 44in

Length = 14in

Unknown:

Width of the rectangle = ?

Solution:

The parameters given can be used to determine the unknown dimension;

Perimeter of a rectangle = 2 (L + W)

L is the length

W is the width

Input the parameters and solve;

44 = 2 (14 + W)

44 = 28 + 2W

2W = 16

W = 8in

The width of the rectangle is 8in
