The perimeter of a rectangle is 72 inches, and its length is 20 inches. What is the width of the rectangle?

Correct Answer : 16

P=2×(length + width)

Given that the perimeter (P) of the rectangle is 72 inches and the length is 20 inches, we can substitute these values into the formula and solve for the width (W):

72 inches=2×(20 inches + width)

First, let's simplify the equation:

72 inches=40 inches+2×width

72 inches−40 inches=2×width

32 inches=2×width

Now, let's divide both sides by 2 to isolate the width:

width=32/2 inches​

width=16 inches

Therefore, the width of the rectangle is 16 inches.
