400 square feet

Right.

80 ft. because a square must be equal on all sides, otherwise itâ€™s a rectangle. Each side must be 20 ft. because the square root of 400 is 20 (what times itself equals 400, 20 x 20). If each side is 20, and there are 4 sides, do 20 x 4 for an answer. That's the explanation.

but what is c.
