Which statement best describes the area of triangle abc shown below?

a. it is twice the area of a square of side length 4 units.
b. it is one-half the area of a square of side length 4 units.
c. it is twice the area of a rectangle with sides 4 units × 3 units.
d. it is one-half the area of a rectangle with sides 4 units × 3 units.

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.

u also answered this so i think u would know but i am here to
