HELP GIVE ME INSTRUCTIONS ON HOW TO DO THIS EXPLAIN IT AS IF YOUR TELLING IT TO A PERSON WHOS NEVER DONE THIS PLZZ I NEE IT SHORT I GOTTA WRITE IT ON PAPER

Answer 1

Explanation:

`\text{Okay you have parallelogram and a half circle. The area of a circle is}\\ \\ A=\pi r^2 \\ \\ \text{The area of the parallelogram is the average of the bases times its height}\\ \\ A=h(b2+b1)/2\text{ so the total area is}\\ \\ A=\pr^2/2+h(b2+b1)/2\\ \\ r=10,\ h=14,\ b1=20,\ b2=32\\ \\ A=\pi 10^2/2+14(20+32)/2\\ \\ A\approx 521.1 mm^2`

Answer 2

521 mm²

Explanation:

There are two shapes making this composite shape - a half circle and a trapezoid. The formula for the area of a circle is pi times r-squared. (
`\pi`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 157)

The formula for a trapezoid is (b1+b2)/2 time height. The bottom base is 32. The top base is 20. 32+20=52. 52÷2=26. 26x14=364

157+364= 521 mm²
