Question

The length of a rectanglewith area 54 square centimeters is 9 centimeters. What is the perimeter of the rectangle, in centimeters?

Answer 1

So, first we have to find the width.

Area of a rectangle = length * width

54 = 9 * width

width = 6cm

Now we can plug this into the perimeter formula.

2w + 2l = P

P = 2(6) + 2(9)

P = 12 + 18

P = 40
