### Question 10:

### Explanation:

So, area of the square = (2a)^{2} = 4a^{2}

The unshaded region is basically the two semicircles.

So, area of unshaded region = area of circle = (22/7)*7*7 = 154
cm^{2}

All the cuts add the same length to the boundary as much as they remove.

So, perimeter remains unchanged.

Total smaller triangles = 9

So, coloured part = 2/9

In 3 days, n chickens will always give n eggs.

As oil is less dense than water, the block will have more than half portion immersed.
