The area of a triangle is 33.6 square inches. If the height of the triangle is 4 inches, what is the length of the base?
This is a problem where you have to have the formula in mind to work backwards and solve the problem.
Basically, we know that the area of a triangle is:
A = 1/2 * B * H
Where we have to solve for B.
So, we can input the numbers we already have into the equation:
33.6 = 1/2 * 4 * B
And then we just use simple algebra to solve it.
33.6 = 2 * B
(Divide by two)
16.8 = B
So, the length of the base of the triangle is 16.8 inches.
