Given that carpet squares has sides that are 9 inches long
<u><em>To find: area of carpet square</em></u>
Since given that carpet is of square shape, we can use area of square formula
<u><em>The area of square is given as:</em></u>

Where "s" is the length of side
Given s = 9 inches
Substituting the values in above formula, we get

Thus the area of carpet square is 81 square inches
It should be 11. Consider the side that is 6 is 4 less than the side that is 10. Therefore the side that is x must be 4 less than 15. So it’s 11.
