Hey You!

The formula for area is length × width. So, let's try all of them:

9 × 8 = 72

9 × 9 = 81

9 × 10 = 90

9 × 11 = 99

Judging by all the possible lengths above, the only two answers that would provide an area either equal to 90 of greater than 90 are:

X=10 and X=10

and 11x9=99
So we have to choose the length 10 or 11
