Answer:
645/61
or
10 35/61
or
10.5737704918
Step-by-step explanation:
Area of a parallelogram is base × height
A=b×h
In this situation we know base and area.
645=61×h
To solve for height divide both sides by 61. (dividng area by base)
h=645/61
645/61 = 10 35/61 = 10.5737704918
The area of the semicircle is 14.1372
