Answer:
132m^2 or 144m^2
Step-by-step explanation:
[tex]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[/tex]
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.
