Patterns from vedic square

Look at the following matchstick pattern of squares (see fig.). The squares are not separate. Two neighbouring squares have a common matchstick. Observe the patterns and find the rule that gives the number of matchsticks in terms of the number of squares. (Hint: If you remove the vertical stick at the end, you will get a pattern of Cs.)

The most important text of vedic mathematics is:

A square transparent sheet with a pattern is given. Figure out from amongst the four alternatives as to how the pattern would apper when the transparent sheet is folded at the middle line shown.

A square transparent sheet with a pattern is given. Figure out from amongst the four alternatives as to how the pattern would appear when the transparent sheet is folded along the rnarked line ?
