Question

1. a square serving platter has an area of 124 in.² which is the best estimate of one side length of the platter? a. 31 inches b. 11.6 inches c. 11.8 inches d. 11.1 inches

Explanation:

Step1: Recall area formula for square

$A = s^2$, where $A$ is area and $s$ is side - length. So $s=\sqrt{A}$.

Step2: Calculate side - length

$s=\sqrt{124}$. Since $11^2 = 121$ and $12^2=144$, $\sqrt{124}\approx11.1$.

Answer:

D. 11.1 inches
