You can first find the missing side (the base) of the triangle using Pythagorean theory, then find the are of the trapezoid, subtracting the triangles area, then find the area of the rhombus (which is easy because all the side are the same so no hard calculations for that) then the rectangle.
Hope this helped.
(By the way all the area formulas are online- you just need to google them, in case you forget some)
