129 don’t know what is going on
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.
C) 156cm²
Step-by-step explanation:
1. 6x6=36
2. 6x10=60
3. 60/2=30
4. 30x4=120
5. 120+36=156cm²
144m^2
