The longest bridge in the world is located in china. it is164,800 meters long. another bridge in china is 69,732 meters long.

round each length to the nearest ten thousand to find the answer.

what is the approximate difference between the lengths of the two bridges?

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.
