Question

The area of a rectangle is 100 square inches and one side is 20 inches long. Find the perimeter of the rectangle.

Answer 1

P = 50 inches.

Explanation:

If one side is 20 in, then 20x5 is 100, which makes up the area.

That tells you that one side is 20 inches and another is 5 inches.

Since we know rectangles have four sides, that means that:

20+20+5+5= 50

Answer 2

240

Explanation:

100+100+20+20=240
