a i) 2u/3 is not the same as 2/3u just so you know. The former is correct.
ii) is wrong. it is a triange and a square. Square 3u x 3 = 9u. Triangle: 0.5 x 2u x 3 = 3u. Therefore 12u in total.
b) is wrong too.
A = 0.5bh
20 = 0.5(4)(5u) because you know that it is a straight line down from 5u.
5u = 10
u = 2
