The shaded area can be found by subtracting the of the two unshaded circles from the big circle.

If you take a pencil and trace the outline of the shaded part, you will see that the perimeter is the sum of the circumference of the big circle and the 2 smaller circles.

Here's a repost from 9 May: The challenge in this question is finding the area of the two shaded triangles. Each shaded triangle = area big triangle - area SXT = half area of square - 1/2x10x6 = 20. Total area of two shaded triangle is 40. The shaded area in the square TMNO is more straightforward.

Thanks Vei Li! Although I find it hard to assume that the point bet P and Y, to point X to point T, is a straight line. A piece of info like that should be stated in the question? And not left to us to assume?

Yes, you are right. Good point raised 😊

Why is angle FEC = 90? EFGH is a rhombus, not a square right?

This rhombus is actually a sq. My kid got a similar question during his mid yr paper too. From the sch question then I know how to do this question.

How to assume that this rhombus is a square? There must be a reason to support this right?

This right angle is show from the original question. It's not drawn by anyone of us.
