Big rectangle
3x-4 (2x+2) = 6x^2-8x+6x-8
=6x^2-2x-8 = 3x^2-x-4
Small rectangle
(X-3) (x-6) = x^2-3x-6x+18
=x^2-9x+18
Big-small= 2x^2+8x-22 is the area of the shaded region

Answer: 12 sections of 1/16 acre
Step-by-step explanation:
We want to find how many sections of 1/16 acre we can have in a total area of 3/4 acre.
This is equal to the quotient between 3/4 and 1/16
Remember that if we have two rational numbers (a/b) and (c/d) the quotient can be writen as:
(a/b)/(c/d) = (a/b)*(d/c) = (a*d)/(b*c)
The quotient we want to solve is:
(3/4)/(1/16) = (3/4)*(16/1) = (3*16)/4 = 12
Then you can have 12 sections of 1/16 acre
