Suppose you have 48 feet of fencing to enclose a rectangular dog pen. the function a = 24x-x2, where x = width, gives you the area of the dog pen in square feet. what width gives you the maximum area? what is the maximum area?

We are given

where

x is width of rectangle

A is area of rectangle

Since, we have to maximize it

so, we will find it's derivative

and then we can set it to 0

and then we can solve for x

now, we can set it to 0

and then we can solve for x

So, width is 12  feet

Maximum area:

we can plug x=12

So, the maximum area is

................Answer

175

step-by-step explanation:

2 inches x 10 miles = 200 miles - 3 inches = 175
