Start with

We observe that both fractions are not defined if
. So, we will assume
.
We multiply both numerator and denominator of the first fraction by 3 and we sum the two fractions:

We multiply both sides by
:

We move everything to one side and solve the quadratic equation:

We check the solution:

which is true
Unlikely because certain would be 100% which is wrong
The answer is 7 because it goes 10th 100th and the thirty one is thousands
How you would solve it is by 8 multiplied by 4.
The formula B*H
So the answer is 32cm squared.
