Answer:
Inverse variation
Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent an inverse variation if it can be expressed in the form \(y*x=k\)
Let
x-----> the length of the rectangle
y-----> the width of the rectangle
The area of the rectangle is equal to
\(A=xy\)
If the area of a rectangle stays constant
then
\(A=k\)
so
\(k=xy\) ------> represent an inverse variation
If the length increase------> the width decrease
If the length decrease------> the width increase
