Answer:
A
Explanation:
First we need to find the perimiter of a parallelogram
Side A is the slanted line,
Side B is the 2 horizontal lines.
The equation for this is 2(a+b)
Let's plug in the measurements:
2(18+27) =
2(45) =
90
So the parallelogram is 90 now we have the perimeter of the semi cirlce already which is 18
90 + 18 = 108
Hope this helps :)
