Question

5. Below is a model of the infield of a baseballstadium. How long is each side of the infield?oth a perfectquare rootnumbers?A= 81 in.?

Answer 1

We have that the area of the infield is 81 in2.

This area is a square, which means it has equal sides, and its area is:

`\text{Area}=side^2`

If the area of the square is 81 in2, we have that:

`\begin{gathered} \text{side}^2=81 \\ \text{side}=√(81) \\ \text{side}=9\text{ in} \end{gathered}`

So the side of the infield is 9 inches.
