Answer:
C. ![52\sqrt{3}\ ft^2](https://tex.z-dn.net/?f=52%5Csqrt%7B3%7D%5C%20ft%5E2)
Step-by-step explanation:
Use formula for the area of trapezoid
![A=\dfrac{a+b}{2}\cdot h,](https://tex.z-dn.net/?f=A%3D%5Cdfrac%7Ba%2Bb%7D%7B2%7D%5Ccdot%20h%2C)
where a is the smaller base, b is the larger base and h is the height.
From the diagram,
![a=11\ ft\\ \\b=15\ ft\\ \\h=4\sqrt{3}\ ft](https://tex.z-dn.net/?f=a%3D11%5C%20ft%5C%5C%20%5C%5Cb%3D15%5C%20ft%5C%5C%20%5C%5Ch%3D4%5Csqrt%7B3%7D%5C%20ft)
So, the area of trapezoid is
![A=\dfrac{11+15}{2}\cdot 4\sqrt{3}=13\cdot 4\sqrt{3}=52\sqrt{3}\ ft^2](https://tex.z-dn.net/?f=A%3D%5Cdfrac%7B11%2B15%7D%7B2%7D%5Ccdot%204%5Csqrt%7B3%7D%3D13%5Ccdot%204%5Csqrt%7B3%7D%3D52%5Csqrt%7B3%7D%5C%20ft%5E2)
Answer:
D
Step-by-step explanation:
Answer: A. 14 miles each day.
Step-by-step explanation:
Day 1 : 15 miles
Day 2 : 10 miles
Day 3 : 7 miles
15 + 10 + 7 = 32 miles
60 - 32 = 28 miles
2 days left
28/2 = 14
14 is less than 18
