Answer 1

the real answer is 48 i just took this test

Answer 2

Answer: The correct answer is 20 inches for the perimeter.

At the beginning the length and width are 8 in by 10 in. We are going to add 0.5 inches on each side of the length and width. That means that each of the sides will increase by 1 inch.

Our new measurements are 9 by 11.

Add up all for sides to find the perimeter.

9 + 9 + 11 + 11 = 20 inches
