Knowing how to calculate the area of a triangle is key for the CSET Multiple Subjects exam. In this lesson we will jump right in by solving two types of triangle problems you are likely to see on your CSET exam. You will then watch two videos on the subject.

Problem #1: If the height of a triangle is ten inches less than the length of its base, and if the area of the triangle is 100 square inches, find the base and the height.

The area of a triangle is given by the formula:

the area of a triangle for the CSET

Where “b” is the base and “h” is the height (or “altitude”). We are given that the height is ten inches less than the base, therefore:
h = b – 10

Since we are given that the area is 100 square inches, we can plug our h formula into the area equation:
