Consider the problem below.
1. A rectangular lot has a width of x and a length of x + 3. What is the area of the rectangular lot?
To solve this problem, we need to find the area of the rectangular lot. We need the skill in multiplying
polynomials since the area of a rectangle uses multiplication
Take note that the area of a rectangle has a formula of Area = length x width.
Therefore in finding the area of the rectangular lot, we need to multiply its length by its width.
A = iw
where A is the area, I is the length and w is the width.
Hence, the area of the rectangular lot is
A=lw
A = (x + 3) x or A = x (x + 3)
