81/3 beacuse you are splitting up 81 among 3 equal rows
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
X+5=18
first get rid of the 5
so X+5-5=18-5
which makes X=13
