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