Question

The area of a square-shaped rug is 81 square feet. If the rug is 9-feet long, what is its perimeter? Explain.

Answer 1

The perimeter is 36 as if the rug is square that means that all the sides are equal and so all the sides must be 9 feet too. If all the sides are added together then they add up to 36.

Answer 2

the correct answer is 9 because u need to divide 9 into 81 which equals 9.
