Understanding √200 ≈ 14.14: The Simplified Guide to Square Roots
When it comes to math, square roots are often puzzling but incredibly useful. One commonly encountered square root is √200, which roughly equals 14.14. In this article, we’ll explore exactly what √200 means, how to approximate its value, why 14.14 is the accepted approximation, and how understanding square roots like this can simplify everyday problem-solving.
Understanding the Context
What Does √200 Mean?
The square root of a number, denoted by √, answers the question: “What number multiplied by itself gives the original number?” So, √200 asks, “What number multiplied by itself equals 200?”
Mathematically, this means solving for x in the equation x × x = 200.
Why Is √200 Not a Whole Number?
Key Insights
Unlike perfect squares (such as √144 = 12), 200 is not a perfect square. When √200 isn’t a whole number, we use approximations to express it in decimal form. Among the common estimates, 14.14 is particularly handy because it balances accuracy and simplicity.
How to Approximate √200 to 14.14
To calculate √200 precisely, we rely on estimation methods or a calculator:
- Since 14² = 196 and 15² = 225, we know √200 lies between 14 and 15.
- Subtracting: 200 − 196 = 4; 225 − 200 = 25
This tells us √200 is closer to 14.

Enter a refined approximation:
14.1² = 198.81
14.2² = 201.64
So √200 is between 14.1 and 14.2 — closer to 14.1.
Using a calculator, √200 is approximately 14.1421…, which rounds to 14.14 for most practical purposes.
Why Use 14.14 Instead of a Longer Decimal?
While √200 is nearly 14.1421, using 14.14 provides a concise and accurate enough value for everyday purposes. Whether in construction, cooking, or physics, this precision balances ease and usefulness — especially in contexts where exact decimals aren’t critical.
Practical Applications of √200 ≈ 14.14
- Geometry: Calculate diagonals in squares or rectangles. For example, a square with side 10 has diagonal √200 ≈ 14.14.
- Engineering and Design: Useful for scaling or comparing measurements in design.
- Basic Algebra: Approximate roots when exact answers aren’t available — ideal for mental math or simplified calculations.
