Answer: 29 cms
Explanation:
since the shape is a compound shape we have to find area of each individual shape
so first label the rectangle as A and the small triangle as B and the larger triangle as C
A= length * width
= 2*8
= 16cm
B= 1/2 b*h
= 1/2 3*2
= 1/2 6
= 3
C= 1/2 b*h
= 1/2 4*5
= 1/2 20
= 10
add all (A+B+C)
16+3+10= 29cms
