What is the perimeter of a rectangle with an area of 96 m2 and whose width is 8 m?

We need to find the length first before we solve for the perimeter.

The formula in finding the length of a rectangle is area divided by width.

96 \[tex]m^{2} [/tex] ÷ 8
12

The formula in finding the perimeter of a rectangle is 2(length) + 2(width).

P =  2(12) + 2(8)
      24 + 16
      40

The perimeter of the rectangle is 40 m.
