Re: 5 Star Questions
Answer to #17:-
The parallel sides are 60 cm and 46 cm.
The non-parallel sides are 13 cm and 15 cm.
Let the Trapezium be named ABCD where AB=46 cm, BC=15 cm, CD=60 cm, and DA=13 cm.
AB || CD.
Draw AE parallel to BC where E is a point on CD. Therefore, ABCE is a parallelogram, where AB=CE=46cm, BC=AE=15 cm. Area of the parallelogram = 46 x 15 = 690 sq.cm.
In triangle ADE, AD=13 cm, AE=15 cm, and DE=60cm - 46 cm = 14 cm.
Area of triangle ADE, where S=(13+14+15)/2=21 cm is
Therefore, total area of Trapezium ABCD is 690 sq.cm + 84 sq.cm = 774 sq.cm.
To JaneFairfax : Please correct me if I am wrong. I tend to make a lot of mistakes in a hurry. Its too difficult to detect these mistakes when I check the second time.

Re: 5 Star Questions
Answer to #22:-
Correct, Identity!
Identity, I try not to use the same image twice. But then, there are two factors I wish to tell you. My fading memory as a result of my age fails sometimes. Second, there's a limited stock to choose from, and I keep rotating! 
Thanks for your observation, I shall try my best to make amends
