Answer:
D
Step-by-step explanation:
The formula for the area of a square is:
[tex]A=s^2[/tex]
Where A is the area and s is the side length.
We already know that the area is 289 square inches. So, substitute 289 for A:
[tex]289=s^2[/tex]
So, to find s, our side length, let's take the square root of both sides:
[tex]s=\sqrt{289}[/tex]
So, our answer would be D.
And we're done!
Further notes: Each side length will be √289 or 17 inches.
