Find the approximate side length of a square game board with an area of 105in2.
alukav5142 [94]

Answer:

Approximately 10.2 inches

Step-by-step explanation:

The area of a square is given by the formula:

A=s^2

Where A is the area and s is the side length.

Since we already know that the area A is 105, substitute:

105=s^2

Now, take the square root of both sides:

s=\sqrt{105}

Use a calculator:

s\approx10.2470

So, the side length is approximately 10.2 inches.
