Here is a geometrical puzzle of highschool level. Try to solve it.
There is a semicircular plot of land with radius R. A square garden is to be prepared in this semicircular region such that two vertices of the square are on the semicircular arc and remaining two vertices are on the diameter. What will be the area of the square in terms of radius R ?
If you get the answer then place it as a comment to my post. You require a Google registration for that. I will post the answer with solution on August 12.

SOME HUMOUR
- "Women are expert mathematicians. They always divide their age by two, multiply their husband's income by five and add a few years to the age of their friends !" (Einstein's opinion)

Try it and you will get some funny numbers ! Let me give one for example...
111111111 x 111111111 = 12345678987654321
Isn't it funny ?
- 1111 x 1111
- 11111 x 11111 OR
- 111111111 x 111111111
Try it and you will get some funny numbers ! Let me give one for example...
111111111 x 111111111 = 12345678987654321
Isn't it funny ?
