Answer:
99
Explanation:
Take the whole shape apart, now, multiply every part on it using the formulas for each.
The area of the two triangle parts is 7.5+7.5=15
the side on the left would be found by doing 5*6=30
the middle side would be 6*6=36
and the right side would be 6*3=18
Add it all up to get 15+30+36+18=
15+66+18=
81+18=
99
