Answer:
The area of rectangle is changing at the rate of 33 square inches per second.
Step-by-step explanation:
We are given the following information:
Let W be the width of the rectangle and L be the length of rectangle.
Rate of change of width = 
Rate of change of length =
We have to find rate of change of area at W = 2 and L = 3.
Rate of change of area = 
Area of rectangle = Length × Width

Putting the values, we get

The area of rectangle is changing at the rate of 33 square inches per second.
