Answer:
99 cm2
Step-by-step explanation:
1. to break this up a bit first find the area of the base
10*2 = 20
2. now 2 triangular sides with the base of 2
2*8/2= 8 (each triangle is 8 cm2)
there's two of them so it's 16
3. now the last two triangular sides
10*6.3/2=31.5
there's two of them so it's 63
4. add it all up: 20 + 16 + 63 =99
