There are two shapes making this composite shape - a <u>half circle</u> and a trapezoid. The formula for the area of a circle is pi times r-squared. (r²)
Since the diameter of the circle is 20, the radius is 10. So pi times 10 squared
3.14159265358x100=314.159265358
Half of that is 157.079632679 (Round to <u>157</u>)
The formula for a <u>trapezoid</u> is (b1+b2)/2 time height. The bottom base is 32. The top base is 20. 32+20=52. 52÷2=26. 26x14=<u>364</u>
