Answer:
<h2>This is not a direct variation.</h2>Step-by-step explanation:
Direct variation:
<em>mathematical relationship between two variables that can be expressed by an equation in which one variable is equal to a constant times the other.</em>
<em>(y varies directly with x with a constant variation of k)</em>
By definition, the area is given by:
Where,
w: width
l: length
We have two expressions for the length:
Since the length is the same, we equate both expressions:
From here, we clear the value of c:
Then, we have that the width is given by:
Substituting the value of c we have:
Finally, the area is given by:
