Question

Jason's square bedroom has an area of 112 square feet. The length of one

of his room is between what two whole numbers?
Multiplying Radicals.

Answer 1

The perfect square before 112 is 100.
The perfect square after 112 is 121.

Square root of 100 < square root of 112 < square root of 121

Square root of 100 = 10 and square root of 121 is 11

10 < square root of 112 < 11

So the number is between 10 and 11
