Find b:

b
C

20

Step-by-step explanation:

We can calculate the value of b using Euclidean theorem

b^2 = 16 × 25 ➡ b^2 = 400 and b = 20

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.
