Question

WILL GIVE BRIANLINEST

Answer 1

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 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
