D 81 in.²

Answer 1

I'm pretty sure that the answer is  81in.2

Answer 2

D.
`81\text{ inches}^2`

Explanation:

We have been given that a square measures 9 inches on each side.

We will use area of square formula to solve for our given problem.

`\text{Area of square}=a^2`, where a represents the length of each side of square.

Upon substituting
`a=9\text{ inches}` in above formula we will get,

`\text{Area of square}=(9\text{ inches})^2`

`\text{Area of square}=81\text{ inches}^2`

Therefore, the area of the square is
`81\text{ inches}^2` and option D is the correct choice.
