Question

find the approximate side length of a square game board with an area of 102 in².

□ in
(round to the nearest inch as needed.)

Explanation:

Step1: Recall area formula for square

$A = s^2$ (where $A$ is area and $s$ is side - length)

Step2: Solve for side - length

$s=\sqrt{A}$

Step3: Substitute given area

$s = \sqrt{102}$

Step4: Calculate and round

$\sqrt{102}\approx10.1$, rounding to nearest inch gives 10 in.

Answer:

10 in
