## How to Calculate the Area of a Triangle Part 2

We continue our discussion on how to find the area of a triangle. In the previous post, we have learned where the formula for the area of a triangle came from. We have studied that a triangle with area $A$, base $b$ and height $h$ is

$A = \displaystyle \frac{bh}{2}$

We continue our discussion with the third example in this series.

Example 3

What is the base of a height 7 and area 8.75 square centimeters?

Solution

$A = \displaystyle \frac{bh}{2}$

$8.75 = \displaystyle \frac{b(7)}{2}$

Multiplying both sides by 2, we have  » Read more
