Answer
Inverse Variation
Work Step by Step
A quick way to recognize direct and inverse variation is to ask, "as x goes up in value, what does y do?" If y goes up, then it is a direct variation. If y goes down, then it is an inverse variation.
In this situation, the area of each rectangle is $24 cm^{2}$
Lets think about possible Lengths and Widths:
$l\times w = 24cm^{2}$
$1\times 24 = 24cm^{2}$
$2\times 12 = 24cm^{2}$
$3\times 4 = 24cm^{2}$
$4\times 3 = 24cm^{2}$
And so on. Examining this data, we can see that as our length (x) gets bigger, our width (y) gets smaller. Therefore, this represents an inverse variation.
