\(F= \frac{1}{4} A\) and \(C = \frac{1}{2} D\)
If the dividing walls between each specified area are going to be painted, how many square feet will be painted?
A. 244
B. 260
C. 488

E. It cannot be determined from the information given.
For knowing the length of wall, we require to know the dimensions of the common walls...
But can we know the length of Walls of the structure with area F..
F=1/4*A......A=4F...area of A+F =16*(28-12)=16*16=256..
Thus we can find area of A and F separately but cannot determine the sides of F..
So E
