I think you have to combine like terms to solve this one. (6d - 3d) + (5 - 2) = 3d + 3

A college is planning to construct a rectangular parking lot on land bordered on one side by a highway. The plan is to use 440 f
NARA [144]

Let x represent side opposite to highway and y represent other two opposite sides as shown in the diagram.

The perimeter of the parking lot will be sum of 3 sides that is x+y+y=x+2y.

We have been given that the plan is to use 440 feet of fencing to fence off the other three sides. This means that perimeter of 3 sides is 440.

x+2y=440

x=440-2y

We know that area of rectangle is length times width, so area of parking lot will be A=x\cdot y

Upon substituting value of x, we will get:

A(y)=(440-2y)\cdot y

A(y)=440y-2y^2

Now we will find the derivative of area function as:

A'(y)=\frac{d}{dy}(440y)-\frac{d}{dy}(2y^2)

A'(y)=440-4y

Let us find critical point by equating derivative to 0.

440-4y=0

440=4y

\frac{440}{4}=\frac{4y}{4}

110=y

Now we will substitute this value is equation x=440-2y to solve for x as:

x=440-2(110)

x=440-220=220

Therefore, the dimensions of 220 feet by 110 feet will enclose the maximum area.
