The basic dimensions of any triangle are its area, base, and height.
They're related by the area equation; the area is half of the base times the height, or:
We know the area and the height, so the missing dimension has to be the base. Let's set up an equation by substituting the values the problem gives into the area equation.
Can you solve this equation for

Given:
The area model.
The area of the shape is 82 square units.
To find:
The correct equation for the given situation.
Solution:
We know that, area of a rectangle is
The figure is divided into 3 rectangles. Using this formula, the area of each rectangle is
Now, the total area is equation to 82 square units.
Since the required equation is , therefore, the correct option is C.
