The area of a rectangular parking lot is
The width of the parking lot is
What is the length of the parking lot?
To find : the length of the parking lot.
Answer to Problem 19P
Explanation of Solution
Given information: The area of a rectangular parking lot is
Calculation:
We will factorize the polynomial for the area of the rectangular parking lot by splitting the midle term into two terms whose sum is
Therefore, by splitting the middle term , we get
We know that area of a rectangle is product of its length and width.
Therefore, length of the parking lot is the ratio of its area to its width.
length
Thus, length of the parking lot is
