12.175 is the correct answer
Answer:

Step-by-step explanation:
We know that the equation that models the height of the ball as a function of time is
.
Where the initial speed is 80 feet.
When the ball lands on the ground, its height will be
.
So to know how long it will take the ball to reach the ground, equal h (t) to zero and solve for t.

To solve this quadratic equation we use the quadratic formula.
For an equation of the form:

The quadratic formula is:

In this case

Then


We take the positive solution

I believe its c, sorry if im wrong.
Ur answer is b to the question
The area will be given by the formula
A=1/2ab sin θ
thus
A=1/2 ×90×90sin 25
A=1,711.604 cm²²
