Question

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

Answer 1

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.
