Answer:
You can either choose B or D.
Answer: ![A=944\ ft^2](https://tex.z-dn.net/?f=A%3D944%5C%20ft%5E2)
Step-by-step explanation:
You need to use the following formula that is used to find the area of a trapezoid:
![A=(\frac{M+m}{2})h](https://tex.z-dn.net/?f=A%3D%28%5Cfrac%7BM%2Bm%7D%7B2%7D%29h)
Where "M"and "m" are the bases of the trapezoid and "h" is the height of the trapezoid.
Based on the information given in the exercise, you can identify that:
![M=c=36\ ft\\\\m=a=23\ ft\\\\h=b=32\ ft](https://tex.z-dn.net/?f=M%3Dc%3D36%5C%20ft%5C%5C%5C%5Cm%3Da%3D23%5C%20ft%5C%5C%5C%5Ch%3Db%3D32%5C%20ft)
Knowing these values, you can substitute them into the formula:
![A=(\frac{36\ ft+23\ ft}{2})(32\ ft)](https://tex.z-dn.net/?f=A%3D%28%5Cfrac%7B36%5C%20ft%2B23%5C%20ft%7D%7B2%7D%29%2832%5C%20ft%29)
Finally, you must evaluate in order to find its area. This is:
![A=(\frac{59\ ft}{2})(32\ ft)\\\\A=\frac{1888\ ft^2}{2}\\\\A=944\ ft^2](https://tex.z-dn.net/?f=A%3D%28%5Cfrac%7B59%5C%20ft%7D%7B2%7D%29%2832%5C%20ft%29%5C%5C%5C%5CA%3D%5Cfrac%7B1888%5C%20ft%5E2%7D%7B2%7D%5C%5C%5C%5CA%3D944%5C%20ft%5E2)
The value of x is about 4.7
5x+x-3=9
6x-3=9
cancel out 3 3+3 9+3
6x=12 divide six by 6 and by 12 too.
x=12/6=2
x=2
It would take her 10 hours.
Explanation: 650 divided by 130 is 5 and 2 hours multiplied by 5 hours is 10 hours. Sorry if I got it wrong, but hoped I helped.
