Answer: 140 $in^{2}$

Step-by-step explanation:

The area for a trapeziod is A = $\frac{1}{2}$ (b1+b2)h

We have almost everything we just need the total length of the top base, since it gives us the outer lengths we can find that by simply doing 4+6+15 which turns out to be 25

Now we can plug in our values:

A = $\frac{1}{2}$ (25 + 15) x 7 = 140 $in^{2}$

$gpm = 29.7 \times {d}^{2} \times \sqrt{np}$
this formula is used to determine gpm (gallons per minute) of flow with a known hose diameter (d) and nozzle pressure (np). The constant (29.7) is consistent when figuring flow with in gallons with a know pressure expressed in psi (pounds per square inch).

Scenario example: a firefighter is using a handline to fight fire with an 1 3/4 inch line with a nozzle pressure of 100 psi. How much water is the firefighter flowing when fighting fire?

$gpm = 29.7 \times {1.75}^{2} \times \sqrt{100}$
