The formula for the area of any triangle is as followed:

-------------------------------------------------------------------------------------------------------------
<u>Let Statements:</u>
Let the variable...
→
represent the length of the base of the triangle
→
represent the length of the height of the triangle
-------------------------------------------------------------------------------------------------------------
Using the information provided from the question, we can substitute its values in place of the variables and solve for the last remaining variable:

Distribute the parenthesis<em> (The Distributive Property) </em>:


Reduce the fraction to lowest terms:

Add -6 to both sides of the equation:


Divide both sides of the equation by 2:
