Can u able to solve dis??????????

the long edge is not straight neither are actual triangles.

The explanation is that, in the first diagram, AB is not actually a straight line. It is composed of two sides of a very narrow triangle with area one square. The difference in angle is so small that it deceives the eye at first glance. The correct way of writing this question, by the way, is 'Are you able to solve this?' or 'Can you solve this?' I hope you don't mind this gentle correction: learning to speak and write English correctly is not done in a day and every little helps!

what is this hole thing about. I had a real close look at pictures you uploaded, but I couldn't figure out about what it was. May be I am not too intellectual or intelligent. You should have been bit more descriptive in your post. I am afraid nobody else would be able to solve this mystery, you have put on us. Anways, lets see if somebody is able to come up with some solution. Cheers
