Susan walked for 30 minutes. reggie walked 3 times longer than susan.

which equation could be used to calculate the number of minutes that reggie walked?

let the variable w stand for the number of minutes reggie walked.

a.30.3=w

b.30=w.3

c.30=w+3

d.30 divided by 3 =w

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.
