Question

Estimate the length of one side of a square floor, if the area is 4700 square feet. Give the whole number that is closest to the amount.

Answer 1

The area of a square is equal to its side squared:
\[A=s^2\]Plugging in 4700 for the area gives us:
\[4700 ft^2 = s^2\]Now, square root both sides to give us our side length:
\[s=\sqrt{4700} \approx 68.557 \approx 69 ft\]
