Judy has built a long shelf for her collection of textbooks. Before putting her books on the shelf, she divides the shelf into 4 equal sections. Judy fills 1 section of the shelf with science books. What fraction of the shelf does Judy fill with science books?

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.
