My son came to me with Geometry homework and my old math skills failed me pretty quick. I can recall some of the basics like the pathagorean theorum, figuring area of rectangles/squares, and other very basic geometry, but the section he is working on now involved finding missing sides of triangles, figuring trapezoid areas, and combining a lot of math that I have forgot in my old age. I have attached an example exercise I was helping him with. One of the questions was to figure the triangle and trapezoid side lengths that are missing and area of each for the top of the bedroom, overall bedroom square inches, feet, yards and similar triangle side lengths and area of the hallway. I've attached some of the exercises I'm helping him with too. Appreciate any help that would help the old man help him with the geometry concepts in this exercise. Thanks

Update - I have tried multiple times to upload the class exercise images, but they don't appear to be uploading and attaching to the post. Without those the post is meaningless...
