Answer Is : 392
Step-by-step explanation:
Bottom rectangle: 12*4 = 48 so 48 + 48 = 96
5*4 = 20, 20+20 = 40 , then 12 * 5 = 60. Add them all up together
96+40+60 = 196
Triangle on top : 12*8 = 96, 96/2 48, but 48+48 is 96 so keep 96 and then 5*10 = 50, there is 2 sides so 50 + 50 = 100, add them all up together
96+100 = 196
196+196 = 392
sorry if i'm wrong but it was right for me
