The video tutorial explains how to express the area of a rectangle with given dimensions as a monomial. It begins by defining a monomial and then describes the dimensions of the rectangle. The tutorial proceeds to calculate the area by multiplying the length and width, and finally simplifies the expression to a monomial form, 8xy squared.
