Understanding Rectangle Area and Polynomials

The video tutorial explains how to multiply polynomials using distribution, focusing on a word problem involving the area of a rectangle. Initially, a mistake is made by referring to a triangle, which is corrected to focus on rectangles. The tutorial guides through setting up expressions for the rectangle's dimensions and calculating its area by multiplying the expressions, demonstrating the distribution process.
