Answer:
it should be 12
i think :)
i hope im correct
Step-by-step explanation:
C.
This is because the x vale is clearly after the 6 and the y value is right on 5
Let Surface Area A, a the base edge and h the height:
A = a²+2a√(a²/4+h²)
h=?
pythagorean theorem:
h²=c²-a²
h=√(c²-a²)
h=√(8²-(.7/2)²)= 8
plug it in the above equation A= 11.7ft²
So A is correct
