Mr. Hawk cuts a square matte board that is 15 1/2 inches on each side. He wants to cut an equal border that is 2 3/4 inches wide. What will be the dimensions of the square hole?

Answer 1

To find the dimensions of the square hole, we need to subtract twice the width of the border from each side of the original square.

The width of the border is 2 3/4 inches, so twice the width is 5 1/2 inches.

Subtracting 5 1/2 inches from each side of the original 15 1/2 inch square gives us:

15 1/2 - 5 1/2 = 10 inches

So the dimensions of the square hole will be 10 inches on each side.
