Two ratios that are equivalent to 5/7

You could pick just about anything 3/8 is not the same thing as 5/7 and neither is 3/4

Something that is equivalent would be something like 10/14 or 20/28

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.
