Step-by-step explanation:
AA congruency theorem
AA is angle angle
The picture gives (( so that measns that (( and (( are congruent angles. The same with the (, it. is congruent to the other (.
First find the area of the triangle,
(8.4 x 24)/2 = 100.8
Then find the area of the parallelogram,
24 x 12 = 288
Then add both,
100.8+288 = 388.8 yd^2
The correct answer is the 2nd one
