How to Find Square Root of 217?
Value of √217 by Long Division Method
Explanation:
- Forming pairs: 02 and 17
- Find a number Y (1) such that whose square is <= 2. Now divide 02 by 1 with quotient as 1.
- Bring down the next pair 17, to the right of the remainder 1. The new dividend is now 117.
- Add the last digit of the quotient (1) to the divisor (1) i.e. 1 + 1 = 2. To the right of 2, find a digit Z (which is 4) such that 2Z × Z <= 117. After finding Z, together 2 and Z (4) form a new divisor 24 for the new dividend 117.
- Divide 117 by 24 with the quotient as 4, giving the remainder = 117 - 24 × 4 = 117 - 96 = 21.
- Now, let's find the decimal places after the quotient 14.
- Bring down 00 to the right of this remainder 21. The new dividend is now 2100.
- Add the last digit of quotient to divisor i.e. 4 + 24 = 28. To the right of 28, find a digit Z (which is 7) such that 28Z × Z <= 2100. Together they form a new divisor (287) for the new dividend (2100).
- Divide 2100 by 287 with the quotient as 7, giving the remainder = 2100 - 287 × 7 = 2100 - 2009 = 91.
- Bring down 00 again. Repeat above steps for finding more decimal places for the square root of 217.
Therefore, the square root of 217 by long division method is 14.7 approximately.

Square Root of 217 Solved Examples
-
Example 1: Solve the equation x2 − 217 = 0
Solution:
x2 - 217 = 0 i.e. x2 = 217
x = ±√217
Since the value of the square root of 217 is 14.731,
⇒ x = +√217 or -√217 = 14.731 or -14.731. -
Example 2: If the surface area of a cube is 1302 in2. Find the length of the side of the cube.
Solution:
Let 'a' be the length of the side of the cube.
⇒ Area of the cube = 6a2 = 1302 in2
⇒ a = ±√217 in
Since length can't be negative,
⇒ a = √217
We know that the square root of 217 is 14.731.
⇒ a = 14.731 in -
Example 3: If the area of a square is 217 in2. Find the length of the side of the square.
Solution:
Let 'a' be the length of the side of the square.
⇒ Area of the square = a2 = 217 in2
⇒ a = ±√217 in
Since length can't be negative,
⇒ a = √217 = 14.731 in
