At the movie theater the blaine family spent $22.00 for twoadult tickets and three child tickets. the hooper family spent $18.50 for one adult ticket and four child tickets. how much did the hu family spend for three adult tickets and one child ticket?

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.
