Elena said that finding 10% of 2,340 and multiplying that
number by 3 is the same as finding 30% of 2,340. Is she
correct? Explain why or why not. Then tell how to find the
percent.

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.
