Don't repost questions so fast.
For question one.
Use what you know to split the complex figure apart into rectangles.
Just to give you some hints:
for question 1, add 11*14 with (20-11)*9
for question two do the same thing with the splitting method.
First one ...we have two rectangles
The top rectangle has the dimensions (11) x (14 - 9) = 11 x 5 = 55 cm^2
The bottom rectangle has the dimensions 20 x 9 = 180 cm^2
Total area = [55 + 180] cm^2 = 235 cm^2
