Answer:
Step-by-step explanation:
A = 126.5488
the formulas of:
circle: π r 2
rectangle: b x h
triangle: b x h / 2
Substitution:
CIRCLE:
3.1416 x 6 2
3.1416 x 36 = 113.0976 / 2 since it is a semicircle, which would result in 56.5488
RECTANGLE:
8 x 7 = 56
TRIANGLE:
2 X 7/2
14/2 = 7
then you add the results
56.5488 + 56 + 7 + 7 = 126.5488
(since they are 2 triangles)
ion
-2 and -8
-2 + (-8) = -10
-2 * -8 = 16
18
Just divide both sides by - 64
