I see you scribbled B+C makes up half of the rectangle. That's right! So B+C is 1/2, then you can find what fraction of the rectangle triangle D is. From there, you can solve for the ratio.

For (a) and (b), use Pythagoras theorem to find x and then you can find (y+4). Try it!

I tried Pythagoras theorem. X physically look longer than BD but turns out to be 3 cm.

Yes, I think the setter wants to confuse students... But nevertheless, x is 3cm. Then you can find (y+4), again, using Pythagoras theorem.
