Consider the number you are calculating the square root of as the area S of a square. Because a square's area is L 2 where L is the length of one of its sides, therefore, by trying to find the square root of your number, you are trying to calculate the length L of the side of that square. Let's use an example. 2  We want to find the square root of 400 by hand. 3  To begin, we would divide the number into perfect square factors. 4  Since 400 is a multiple of 100, we know that it's evenly divisible by 25 - a perfect square.
