Question

Will is planning to build a square pool in his yard. He needs an area greater than 50 square feet but less than 75 square feet. Estimate the length of each side of the pool to the nearest whole number.

Answer 1

8

Explanation:

If you want a square pool each side is going to be the same length. So if we check each length we can find the correct one that is between 50 and 75.

1 x 1 = 1

2 x 2 = 4

3 x 3 = 9

4 x 4 = 16

5 x 5 = 25

6 x 6 = 36

7 x 7 = 49

8 x 8 = 64

9 x 9 = 81

As we can see if a pool has side length of 8 feet, we will have a correctly sized pool.
