Area of a rectangle formula: A=LW
substitute the values in:
122.12=L(8.7)
Solve for L. Divide by 8.7 to isolate L.
L≈14.04 feet
I believe the answer is D
Answer:
what type of qwestion is this? Area of triangle is (1÷2) base ×height
Answer:

Step-by-step explanation:

We know that the formula for the Area, A of a triangle is given as:
.....(Equation 1)
In our question we already know that
and

Substituting these values in (Equation 1) we will get:

Multiplying both sides by 2 we will get:

In-order to find base we will isolate it by dividing both sides by 15. Thus, we get:

Thus, the answer is, base=27 mm.
