Greetings!
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:

Answer:

Step-by-step explanation:

Multiply both sides of the equation by 99, the least common multiple of 9,39,3.
m + 6 =21
Subtract 6 from both sides.
m = 21 - 6
Subtract 6 from 21 to get 15.
m=15
It would be 0.2222 so it's your answer
The answer to your question is 57.6
