The 525 question is 3m but depends on whether you get method mark...

I think the answer is 585

We know that length is 6 cm.


So Area of Q and R = 1/2 x B x H = 1/2 x 6 x 6 = 18 cm sq
Since Q = 6 cm sq, R = 12 cm sq

Therefore, S = 36 - (4+6+12) = 14 cm sq

Fraction of S to Whole Figure will be 14/36 = 7/18
