Final answer:
The correct answer is option C) 20.021 feet.The base of the parallelogram is approximately 18.011 feet.
Step-by-step explanation:
To find the base of a parallelogram, we can use the formula for the area of a parallelogram which is given by: Area = base x height. Given that the height is 10.5 feet and the area is 189,112 square feet, we can substitute these values into the formula and solve for the base.
189,112 = base x 10.5
Dividing both sides of the equation by 10.5, we get:
base = 189,112 / 10.5
base ≈ 18,010.476 approximated to the nearest thousandth.
Therefore, the base of the parallelogram is approximately 18.011 feet, which corresponds to option B).
