Documenting FOIL Expansion Steps for a Workspace Blueprint

Imagine you are working as a design assistant at a construction planning firm. A colleague has created a blueprint for a new storage room with dimensions represented by (x+3)(x + 3) and (x+7)(x + 7) meters. To help them double-check their area calculations, write a brief explanation recalling each step of the FOIL method to expand (x+3)(x+7)(x + 3)(x + 7). In your essay, define what each letter of the FOIL acronym stands for, list the specific product result for each of those four steps before simplifying, and provide the final combined, simplified expression.
