You have to put numbers for what you want the area or perimeter to be and do accordingly
The first reaction represented is a decomposition reaction due to the fact the bonded pair are being split apart.
The second equation is a single displacement because the B and C have switched places, which is the only change making it a single displacement. If there had been another bond and A had also moved, it would be double.
Since 3 squared is 9 and 4 squared is 16, the square root of 13 will fall somewhere between 3 and 4
