Asked Mar 17, 2019
A rectangle has a length that is increasing at a rate of 10 mm per second with the width being held constant. What is the rate of change of the area of the rectangle if the width is 8 mm? (Do not include the units in your answer.)

Expert Answer

Step 1

We have to find rate of change of area .

Information is given below:

Step 2

We will use following rule of derivative.

Rules are given below:

Step 3

Now with the help of above derivative rules  we will diiferentiate area equation it will give relation between dA/dt a...
