Square Root of 225 by Long Division Method

Here’s how to find the square root of 225 by the long division method:

Step 1: Start with the number 225 and group the digits into pairs from the right. So, from 225, we choose 25 as a pair, and 2 stands alone.

Step 2: We begin by dividing 2 with a number such that the number × number gives 2 or a number less than that.

Step 3: After dividing, we obtain 1 as the quotient and 1 as the remainder.

Step 4: Next, we bring down 25 for division so that the new dividend becomes 125.

Step 5: We double the divisor, meaning 1 + 1 = 2, and write this as one of the digits for the new divisor.

Step 6: Identify a number that can be placed next to 2 to obtain a two-digit number as a new divisor. This number should also be multiplied by itself to produce 125 or less than that.

Step 7: We find that 5 is the number, such that 25 × 5 gives 125.

Step 8: Finally, we obtain the quotient 15 and the remainder as 0.

By following these steps, we have successfully found that the square root of 225 is 15 using the long division method.

225 is Perfect Square Root or Not

A perfect square is a number that can be expressed as the product of an integer multiplied by itself. In the case of 225, it can be expressed as 15 × 15, which equals 225. Therefore, 225 is indeed a perfect square.
