The house will be 3 1/2 feet tall. how many inches tall will the house be?

12 inches in a foot

12 times 3 is 36

half a foot is six inches

so your answer is 42 inches

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.
