Question 10:
Explanation:
So, area of the square = (2a)2 = 4a2
The unshaded region is basically the two semicircles.
So, area of unshaded region = area of circle = (22/7)*7*7 = 154 cm2
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.
