Using Heron's formula:
A = √(p(p-a)(p-b)(p-c)) where a,b,c are the sides of the triangle and p is half the perimeter.
The answer is B. 149.4 square units.
The relationship between the length & the width of the closet and the length of the wall is an illustration of a linear equation.
- <em>The equation for f(l) is: </em>
<em>.</em> - <em>The desired length and width are 8m and 4m</em>
<em />
Given that:

Divide both sides by 2

<u>Equation of f(l)</u>
The sum of the length and the width is represented as: f(l).
So, we have:

Substitute 


See attachment for the graph of f(l)
<u>The desired dimension</u>
From the question, we understand that the total length is 12m.
This means that:

So, we have:

Divide both sides by 1.5

Recall that:



Hence, the desired length and width are 8m and 4m, respectively.
