The area of a small square patio is 23 square feet. The length of each side of the patio is feet. Between what two whole-number measurements does feet lie?

16 ft and 25 ft

Step-by-step explanation:

The formula for the area of a square is A = s^2, where s is the length of any one side. Your task is to determine two perfect squares that define the side length.

Think: what's the first perfect square smaller than 23 ft? It's 16 ft.

What's the first perfect square greater than 23 ft? It's 25 ft.

Thus, the length of any one side of this square lies between √16 ft and √25 ft, or, equivalently, between 4 and 5 ft.
