Square Roots of Numbers 1 to 30: Easy Table and Guide

The concept of Squares 1 to 100 is a core part of arithmetic and number theory, often used in algebra and geometry. Learning the values of squares from 1 to 100 helps simplify calculations in school exams, competitive tests, and practical scenarios.

What are Squares 1 to 100?

A square number is the product of an integer multiplied by itself. For numbers from 1 to 100, the squares are found by performing \( n \times n \) for each integer value of \( n \) between 1 and 100. Recognizing square numbers is crucial for checking if a value is a perfect square and is especially important when working with square roots and quadratic equations.

Formula and Tricks to Find Squares 1 to 100

The basic formula for the square of a number \( n \) is:

n × n = n²

Some quick tricks to calculate squares include:

• For numbers ending in 5: The square of any number ending with 5 (say, 35) is given by \( (3 \times 4) \text{ and add } 25: (3 \times 4)25 = 1225 \)
• Using algebraic identities: \( (a+b)^2 = a^2 + 2ab + b^2 \). Example: \( 47^2 = (40 + 7)^2 = 1600 + 560 + 49 = 2209 \).
• Memorizing squares of numbers 1 to 20 for easier calculation of larger squares using patterns.

Worked Examples

Example 1: Use the table to find the area of a square park with side 34 m.

1. Area = side × side = 34 × 34
2. From the square 1 to 100 table, 34² = 1156
3. So, the area = 1156 sq. m

Example 2: Calculate (17)² + (19)²

1. From the table, 17² = 289; 19² = 361
2. Add: 289 + 361 = 650

Example 3: If a circle has radius 10 cm, find the area using the square 1 to 100 chart.

1. Area = π × r²
2. From the table, 10² = 100
3. Area = 3.14 × 100 = 314 cm²

Practice Problems

• What is the value of 23² + 6²?
• Find the square of 29 using the table above.
• If the side of a square is 21 cm, what is its area?
• Find a number between 64 and 81 whose square is 100.
• Using the trick for numbers ending in 5, find 45².

Common Mistakes to Avoid

• Confusing squares with square roots (e.g., writing 5 as the square of 25).
• Forgetting to multiply the number by itself.
• Trying to memorize all 100 values at once—focus on small groups or patterns.
• Mistaking squares for cubes.

Real-World Applications of Square Numbers

Square numbers appear in real life when calculating the area of square shapes like rooms, fields, or tiles; in architecture and engineering; and in statistics, such as in standard deviation calculations. They also help in estimating roots and solving quadratic equations in physics and finance.
