Answer:
The answer to your question is Area = 24, letter B
Step-by-step explanation:
Data
ABCD is a rectangle
BE = 4
DC = 12
CE = 5
Process
1.- Calculate the area of the ΔABD
Area ΔABD = base x height /2
= 12 x (5 + 4) /2
= 12 x 9/2
= 54
2.- Calculate the area of the ΔCDE
Area ΔCDE = 12 x 5/2
= 30
3.- Calculate the area of the rectangle ABCD
Area = 12 x 9
= 108
4.- Find the area of the ΔBDE
Area = A rectangle - A ΔABD - A ΔCDE
Area = 108 - 54 - 30
Area = 24
