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.
Original cost of the necklace = $28
Percentage by which the store reduces the price of the necklace = 20%
Amount of discount given
by the store on the necklace = (20/100) * 28
= 28/5 dollars
= 5.6 dollars
So
The price of the necklace after discount = (28 - 5.6) dollars
= 22.4 dollars
Amount of discount on coupon = $2
Then
Price of the necklace after deducting coupon discount = (22.4 - 2) dollars
= 20.4 dollars
So Janet will pay 20.4 dollars for the necklace.
