Answer:
A. 15 sq in
Step-by-step explanation:
So it wants to know the area of the yellow face: we have to subtract that chunk cut out of the bottom right from the larger rectangle.
Area = length x width = 4*4 = 16 sq in. This is the area of the larger rectangle.
Area = length x width = 1*1 = 1 sq in. This is the area of the rectangle that's cut out of the yellow area.
16 - 1 = 15 sq in
