A square sheet of art paper has an area of 576 square inches. What is the minimum side length of an easel that supports the whole sheet of paper?

A. - 24 inches

B. 288 inches

C. 24 inches

D. 17 inches

If you want to find the minimum side length of an easel that will support the whole sheet of paper, just divide the area by 2. Why? We know it's a square. So, the formula for finding the area of a square is A = s^2. Where is s is the side length of the square.

So, dividing by 2 will reverse it.

576 / 2 = 288

So, B. 288 inches is the answer.
