A fraction is a short way to write a division problem.

Whenever you see a fraction, it means

(the top number) divided by (the bottom number).

When you pick up your pencil or your calculator and actually do the
division, the answer to the division is the decimal form of the fraction.

To change that fraction 1/5 to a decimal, divide 1 by 5 .

Then, to change the decimal to a percent, move the
decimal point 2 places that way ==>.

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.
