If a square has an area of 90, then each of its sides is the square root of 90, because Area of a square=s*s where s is the length of a side.
sqrt%2890%29=3sqrt%2810%29
So the fencing needed to enclosed it is the perimeter of the square, which would be 4 times the side length.
4%2A3sqrt%2810%29=12sqrt%2810%29
