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
They both would have a circular base
22x+1 where x would be Gail's age.
Let breadth be x
We know





It doesnot have any real roots
I think it’s D. (don’t quote me on it) good luck hopefully this is helpful !!! :)
