132m^2 or 144m^2

Step-by-step explanation:

$A=a^2+2a\sqrt{\frac{a^2}{4}+h^2 } \\=6^2+2*6\sqrt{\frac{6^2}{4}+8^2 } \\=138.53m^2$

That is the exact answer, so i cant tell you which one to choose, as its close to the middle. But if i had to choose i would choose 144m^2 because its just that litte bit closer.

Step-by-step explanation:

1. 6x6=36

2. 6x10=60

3. 60/2=30

4. 30x4=120
