The answer to this is 81x^2.
With area, you multiple two sides. With a square, all sides are equal and so, you just take 9x and multiply it by 9x.
9 x 9= 81
X x X= X^2
And so, the answer is 81x^2
Answer:
81x^2 sq cm
Step-by-step explanation:
Area formula: length × width
Squares are the same size on all 4 sides, which means because 1 side is 9x cm, all other sides will also be 9x cm.
Area: 9x cm × 9x cm = 81x^2 cm^2
sq = ^2
