Find the area of the rectangle and the 1/2 circle, then subtract the half circle's area from the rectangle's.
Area of the rectangle is 30in.
Area of the 1/2 circle is 19.625.
Subtract
30-19.625
10.375
(Round it to 10.4 in this case)
Solve the equation

So we have:

Factor, 2 numbers of which the sum is -13 and multiplying gives 36, these two are -4 and -9
So solve:

The solutions:
4 and 9
