Question

solve the problems below. be sure to show your thinking. 9. a square sandbox has an area of 115 square feet. estimate the length of one of the sides of the sandbox.

Explanation:

Step1: Recall area formula for square

Let side - length be $s$, $A = s^{2}$, so $s=\sqrt{A}$.

Step2: Estimate square - root

$\sqrt{115}$. Since $10^{2}=100$ and $11^{2}=121$, $s\approx10.7$ feet.

Answer:

Approximately 10.7 feet
