Question

The area of a square is equal to twice the perimeter of the square. Find the area of the square. 8 units2 64 units2 16 units2 32 units2

Answer 1

The answer is 64 units^2 because let the side length equal x.Then the area is x^2 and the perimeter is 4x. So we have the equation x^2=8x. Subtracting 8x form both sides and completing the square we get (x-4)^2=4 so x=8. That means the area is g4.

Answer 2

The answer is 249 square units
