Answer:
52√3 ft ²
Step-by-step explanation:
Formula for area of the trapezoid:
a = Base = 11
b = Base = 15
h = Height = 4√3
Since the height is 4√3 we can turn it into a number:
4√3 = 6.92820323028 = 6.93
Now using the formula:
As you can see that it not a answer choice.
We can turn the answer choice into number:
44√3 ft ² = 76.21023553.. ≈ 76.20
44√3-24 ft ²=52.21023553.. ≈ 52.20
60√3 ft ² = 103.92304845.. ≈ 103.90
52√3 ft ² = 90.06664199.. ≈ 90.07
Thus, the answer is 52√3 ft ²
