How to Find Square Root of 249?
Value of √249 by Long Division Method
Explanation:
- Forming pairs: 02 and 49
- 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 49, to the right of the remainder 1. The new dividend is now 149.
- 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 5) such that 2Z × Z <= 149. After finding Z, together 2 and Z (5) form a new divisor 25 for the new dividend 149.
- Divide 149 by 25 with the quotient as 5, giving the remainder = 149 - 25 × 5 = 149 - 125 = 24.
- Now, let's find the decimal places after the quotient 15.
- Bring down 00 to the right of this remainder 24. The new dividend is now 2400.
- Add the last digit of quotient to divisor i.e. 5 + 25 = 30. To the right of 30, find a digit Z (which is 7) such that 30Z × Z <= 2400. Together they form a new divisor (307) for the new dividend (2400).
- Divide 2400 by 307 with the quotient as 7, giving the remainder = 2400 - 307 × 7 = 2400 - 2149 = 251.
- Bring down 00 again. Repeat above steps for finding more decimal places for the square root of 249.
Therefore, the square root of 249 by long division method is 15.7 approximately.

x2 - 249 = 0 i.e. x2 = 249
x = ±√249
Since the value of the square root of 249 is 15.780,
⇒ x = +√249 or -√249 = 15.780 or -15.780. -
Example 2: If the surface area of a sphere is 996π in2. Find the radius of the sphere.
Solution:
Let 'r' be the radius of the sphere.
⇒ Area of the sphere = 4πr2 = 996π in2
⇒ r = ±√249 in
Since radius can't be negative,
⇒ r = √249
The square root of 249 is 15.780.
⇒ r = 15.780 in -
Example 3: If the area of a square is 249 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 = 249 in2
⇒ a = ±√249 in
Since length can't be negative,
⇒ a = √249 = 15.780 in
