One side of a roof is in the shape of a trapezoid (similar to the one on pizza hut). the top row requires 10 shingles, the second row requires 16 shingles, the third row requires 22, etc. the nth row on the bottom requires 6n + 4 shingles. what is the total number of shingles needed to cover this side of the roof ? a) n2 + 6n b) 3n2 + 7n c) 6n2 + 10 d) 6n2 + 14n

answer rather than having to add and subtract the measurements of the semi-circle, notice that the semicircle to the left of ad is actually identical in area to the blank semicircle-shaped space to the left of bc. so if we transferred the red semicircle into the blank space, we would end up with a square of side length 24 cm. the area of a square is s^2 = 24^2 = 676 cm^2.
