AI Drawing Prompt Reference

Start at the origin and construct a rectangle defined by four points, then translate it vertically three times to create a stack of four aligned rectangles. From this base, replicate the rectangles horizontally and vertically to form a regular grid array. Above the grid and to its right, add strips composed of small squares to represent algebraic area terms. Finally, draw several separate rectangles around the perimeter and include connecting segments to show relationships between parts. The overall layout should clearly illustrate the geometric pattern of binomial products.
