Sarah has a floor plan of the jefferson building. the actual building is 168 feet long. what is the scale factor for the floor plan?
a) 1 in : 6 feet
b) 1 in : 28 feet

c) 1 in : 68 feet
d) 1 in : 96 feet

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.
