Answer:

Step-by-step explanation:
Let's call B at the base of the triangle and call h at the height of the triangle. Then we know that:
The height of a triangle is 5 cm shorter than its base. This means that:
.
The area of the triangle is 25 cm²
By definition the area of a triangle is:

For this triangle we know that
and
. We substitute these values in the equation and solve for B.


Now we use the quadratic formula to solve the equation.
For an equation of the form
the quadratic formula is:

In this case note that: 
Then:



The solutions are:


For this problem we take the positive solution.

Now we substitute the value of B in the equation to find the height h

Answer:
$65.80
Step-by-step explanation:
Divide 26.32 by 8 to find how much is in one gallon.
26.32÷8=3.29
So it's 3.29 per gallon.
Multiply 3 29 by 20.
20×3.29= 65.8
So he would spend $65.80
