The area for a rectangle is length × width. The area for a parallelogram is base × height. The area for a trapezoid is height (base 1 + base 2) ÷ 2. The area for a rhombus is base × height.
Please let me know if you want me to add an explanation as to why this is the answer. I can definitely do that, I just don’t want to waste my time in case you don’t want me to :)
