The length of a rectangle is 9 inches and its perimeter is 48 inches. What is the width of the rectangle?
A. Let x represent the unknown width of the rectangle. Write an equation that can be solved for the unknown measurement.
B. Solve your equation to find the width of the rectangle. Show all your work.

Answer :

A.) Equation of Perimeter of a rectangle (P) = 2(l + w)

48 = 2(9 + x)

B.) Solving: 48 = 2(9 + x)

48 = 18 + 2x

2x = 48 - 18

x = 30/2

x = 15

In short, Width would be: 15 inches

Hope this helps!

9(2) + 2x = 48
18 + 2x = 48
2x = 30
x = 15
