    For the FOIL Method, you have skipped the step that illustrates the method you used although you final answer is correct.

    As of the diagram, you have labelled the sides correctly. However, the areas of each part (ie. The smaller rectangles) are not written on the diagram. Pls check again. Once the areas of each part is found, then use the areas to find the answer to the question.
