Question

What is the least perimeter of a rectangle with an area of 32 square feet

Answer 1

There's 3 possibilities for a rectangle with an area of 32 square feet.
$8 \times 4 \\ 16 \times 2 \\ 32 \times 1$
If 8 x 4, Perimeter =
$2(8) + 2(4) = 24$
If 16 x 2, Perimeter =
$2(16) + 2(2) = 36$
If 32 x 1, Perimeter =
$2(32) + 2(1) = 66$

Hence, the least perimeter is 24 feet.

Hope this helps. - M
