The perimeter of a rectangle is 264 and the length is 72. Find the width

Answer 1

Since the perimeter (p) is two times the length (l) plus two times the width. If w represents the width, then:

p = 2 w + 2 l

Then 264 = 2 w + 2 * 72

Since 2*72 is 144, we can write 264 = 2 w + 144

Use inverse operations to solve this equation:

264 - 144 = 2 w + 144 - 144 (Subtract 144 from both sides of the equation)

120 = 2 w (Recall that 264 -144 is 120)

120/2 = 2w/2 (Divide both sides of the equation by 2)

w = 60 units
