I've modified your drawing a little bit.

Area1 is a trapezoid with the parallel length of 50 and (50 + 300*tan(20°). The height is 300.

Area2 is the rectangle - Area1 - area of the isosceles triangle $= \frac12 \cdot (210-50) \cdot 220$

3. Area 1:
Separate this figure into two shapes: 1.) rectangle of width 50 and hieght 300
and 2.) triangle of base 300 and hieght 300tan(20).

Area 2:
Find the area of the drawn triangle, it has a hieght of 220 and a base of 220tan(20). Then the area of figure 2 is totalarea - area1 - areatriangle.

4. Thanks for the help guys.. been a while since i done maths
