Okay,
We see that there are to shapes- semi circle and trapezoid
Area of the semicircle:
1/2πr^2
r=4.5 cm
A≈31.8 square cm.

Area of the trapezoid=1/2(b1+b2)h
h=2r
h=9cm
b1=9.5cm
b2=12 cm
A=96.75 square cm
A=96.75+31.8
A≈128.55 square cm is your final answer. Hope it help!

Please help! A parallelogram has an area of 396 square centimeters and a height of 18 centimeters.
frosja888 [35]
The area formula for a parallelogram is base*height=area. Make an equation. You know the area and the height, so plug that into the equation, and you get x*18=396. Solve for x by dividing 396 by 18 and you get 22. So, the base is 22cm.
