How to Find Square Root of 351?
Value of √351 by Long Division Method
Explanation:
- Forming pairs: 03 and 51
- Find a number Y (1) such that whose square is <= 3. Now divide 03 by 1 with quotient as 1.
- Bring down the next pair 51, to the right of the remainder 2. The new dividend is now 251.
- 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 8) such that 2Z × Z <= 251. After finding Z, together 2 and Z (8) form a new divisor 28 for the new dividend 251.
- Divide 251 by 28 with the quotient as 8, giving the remainder = 251 - 28 × 8 = 251 - 224 = 27.
- Now, let's find the decimal places after the quotient 18.
- Bring down 00 to the right of this remainder 27. The new dividend is now 2700.
- Add the last digit of quotient to divisor i.e. 8 + 28 = 36. To the right of 36, find a digit Z (which is 7) such that 36Z × Z <= 2700. Together they form a new divisor (367) for the new dividend (2700).
- Divide 2700 by 367 with the quotient as 7, giving the remainder = 2700 - 367 × 7 = 2700 - 2569 = 131.
- Bring down 00 again. Repeat above steps for finding more decimal places for the square root of 351.
Therefore, the square root of 351 by long division method is 18.7 approx.

Square Root of 351 Solved Examples
-
Example 1: Solve the equation x2 − 351 = 0
Solution:
x2 - 351 = 0 i.e. x2 = 351
x = ±√351
Since the value of the square root of 351 is 18.735,
⇒ x = +√351 or -√351 = 18.735 or -18.735. -
Example 2: If the area of an equilateral triangle is 351√3 in2. Find the length of one of the sides of the triangle.
Solution:
Let 'a' be the length of one of the sides of the equilateral triangle.
⇒ Area of the equilateral triangle = (√3/4)a2 = 351√3 in2
⇒ a = ±√1404 in
Since length can't be negative,
⇒ a = √1404 = 2 √351
We know that the square root of 351 is 18.735.
⇒ a = 37.470 in -
Example 3: If the area of a square is 351 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 = 351 in2
⇒ a = ±√351 in
Since length can't be negative,
⇒ a = √351 = 18.735 in
