How to Find Square Root of 424?
Value of √424 by Long Division Method
Explanation:
- Forming pairs: 04 and 24
- Find a number Y (2) such that whose square is <= 4. Now divide 04 by 2 with quotient as 2.
- Bring down the next pair 24, to the right of the remainder 0. The new dividend is now 24.
- Add the last digit of the quotient (2) to the divisor (2) i.e. 2 + 2 = 4. To the right of 4, find a digit Z (which is 0) such that 4Z × Z <= 24. After finding Z, together 4 and Z (0) form a new divisor 40 for the new dividend 24.
- Divide 24 by 40 with the quotient as 0, giving the remainder = 24 - 40 × 0 = 24 - 0 = 24.
- Now, let's find the decimal places after the quotient 20.
- 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. 0 + 40 = 40. To the right of 40, find a digit Z (which is 5) such that 40Z × Z <= 2400. Together they form a new divisor (405) for the new dividend (2400).
- Divide 2400 by 405 with the quotient as 5, giving the remainder = 2400 - 405 × 5 = 2400 - 2025 = 375.
- Bring down 00 again. Repeat above steps for finding more decimal places for the square root of 424.
Therefore, the square root of 424 by long division method is 20.5 approx.

Square Root of 424 Solved Examples
-
Example 1: Solve the equation x2 − 424 = 0
Solution:
x2 - 424 = 0 i.e. x2 = 424
x = ±√424
Since the value of the square root of 424 is 20.591,
⇒ x = +√424 or -√424 = 20.591 or -20.591. -
Example 2: If the surface area of a cube is 2544 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 = 2544 in2
⇒ a = ±√424 in
Since length can't be negative,
⇒ a = √424
We know that the square root of 424 is 20.591.
⇒ a = 20.591 in -
Example 3: If the area of an equilateral triangle is 424√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 = 424√3 in2
⇒ a = ±√1696 in
Since length can't be negative,
⇒ a = √1696 = 2 √424
We know that the square root of 424 is 20.591.
⇒ a = 41.183 in
