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

A is area of rectangle

x is width of rectangle

Since, we have to maximize area

so, we will find derivative

now, we can set it to 0

and then we can solve for x

The width which gives you the maximum area is 12 feet........Answer

now, we can plug x=12 to find area

So, the maximum area is

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

3, nah jk it's 2
