Which is the correct simplification of 5.4 x 10^12/ 1.2 x 10^3 a is 4.5 x 10^7 b is 4.5 x 10^9 c is 45 x 10^6 d is 6.48 x 10^7

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.
