If you want the area of a square with given side, you have to square the length of the side.
So, if the side is 
, the area will be
Answer: The length of minor arc AB = 12.56 units.
Step-by-step explanation: The circle x has its circumference given as 2Pi x r.
A fraction of the circle is given as O/360,
Where O is the angle subtended at the center of the arc AB.
The length of an arc can be calculated by the formula;
Length of arc = O/360 x (2Pi x r)
Length of arc = 60/360 x (2 x 3.14 x 12)
Length of arc = 1/6 x (6.28 x 12)
Length of arc = 12.56 units.
Therefore the length of minor arc AB = 12.56 units
