Side=s area= A=s%5E2
A=s%5E2=126+m%5E2
s%5E2=126+m%5E2 Find square root of each side
sqrt%28s%5E2%29=sqrt%28126+m%5E2%29
s=sqrt%28126%29+m
s=sqrt%289%2A14%29+m
s=3%2A+sqrt%2814%29+m+
The square root of 16 is four and the square root of 12 is about 3.5,
so the square root of 14 should be in the middle (about 3.75) so estimating 3(3.75)=11.25 so each side is about 11.25 m long
Since 11 squared is 121, we could have just estimated a bit over 11 m
