please help asap! it’s area and perimeter of rectangles and parallelograms!

Answer: I don’t know how to solve the area of these shapes. But I know how to find the peeimeter Of this shape.
perimeter=P
finding the P of any shape is like finding the P of a square or rectangle. Is to add up all the sides up like for the 8th one it would be 10+20+20+10 or (10x2)+(20x2)
hope this helps!
