HELP I NEED AN ANSWER ASAP!!
The area of a rectangle is greater than or equal to 90 square centimeters. The width is 9 centimeters and the length is x centimeters. Select the possible value(s) of x.
Choices:
X=8
X=9
X=10
X=11
There can be more than one answer.

Answer 1

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

Answer 2

Oh, I could help
You know the formula of area of rectangle
Aire= widthxlength
we have 9x8=72
9x9=81
10x9=90
and 11x9=99
So we have to choose the length 10 or 11
