Answer 1

Answer:

396 yd^2

Step-by-step explanation:

8X12=96

(96/2)*2=9

10*10=100

100*3=300

300+96=396

Answer 2

Answer:

416 yd^2

Step-by-step explanation:

The formula for the surface area of a triangular prism is

$A=2\sqrt{\frac{a+b+c}{2}(\frac{a+b+c}{2}-a)(\frac{a+b+c}{2}-b)(\frac{a+b+c}{2}-c)}+(a+b+c)h$

where h is the height (10), and a, b and c are the base sides (10, 10, 12).
