Answer:
The area of this composite figure is 
Step-by-step explanation:
we know that
If the composite figure is divided into two congruent trapezoids, then the area of the composite figure is equal to the area of one trapezoid multiplied by two
so
The area of the composite figure is
![A=2[\frac{1}{2}(b1+b2)h]](https://tex.z-dn.net/?f=A%3D2%5B%5Cfrac%7B1%7D%7B2%7D%28b1%2Bb2%29h%5D)

substitute the values


You know that he makes $90 for doing chores, dividing that by 6 and you get that each week he earns $15 for chores.
The volume is proportional to the cube of the radius:
4^3=64
The volume will be 64 times the original value!
