How many sides are to be covered in order to make a complete round of the given figure?
12
The given figure has 12 sides.
The sides are AB, BC, CD, DE, EF, FG, GH, HI, IJ, JK, KL, and LA.
In order to complete a full round, one should reach the same point he started from. i.e., If we start from 'A', we should reach back 'A' to complete one round.
∴ Number of sides to be covered to complete one round = 12
