Step 1: Enter the number in the calculator. Enter 519 in the calculator.
Step 2: Multiply the number by itself using the multiplication button (×). That is 519 × 519.
Step 3: Press the equal to button to find the answer. Here, the square of 519 is 269,361.
Tips and Tricks for the Square of 519
Tips and tricks make it easy for students to understand and learn the square of a number. To master the square of a number, these tips and tricks will help students.
- The square of an even number is always an even number. For example, 6² = 36.
- The square of an odd number is always an odd number. For example, 5² = 25.
- The last digit of the square of a number is always 0, 1, 4, 5, 6, or 9.
- If the square root of a number is a fraction or a decimal, then the number is not a perfect square. For example, √1.44 = 1.2.
- The square root of a perfect square is always a whole number. For example, √144 = 12.
Common Mistakes to Avoid When Calculating the Square of 519
Mistakes are common among kids when doing math, especially when it is finding the square of a number. Let’s learn some common mistakes to master the squaring of a number.
Mistake 1
Calculation errors:
Calculation errors mostly happen when students skip the steps or else swap the digits. To avoid it, students should double-check the answer. They can double-check by finding the square root of the solution they found.
For example, the square of 25 is 625, and the square root of 625 is ±25.
Mistake 2
Errors while using the formula.
The formula to find the square of the number is a². Instead, students may mistakenly use (5 + 1 + 9)² or (500 + 19)². So students should check and use the correct formula and double-check the answers to avoid all the confusion.
Mistake 3
Confusing with square and square root.
Not understanding the concept of square and square root can lead to confusion in students. To avoid it, students should understand the concept that square and square root are inverse operations. The square of 5 is 25, and the square root of 25 is ±5.
Mistake 4
Errors in parentheses.
Ignoring the parentheses when finding the square of a number can lead to errors. So, students should understand parentheses and perform the operations in the correct order to avoid errors.
Mistake 5
Not practicing regularly.
Regular practice is required to master the square of a number. So students should practice regularly to avoid errors.
Solved Examples on Square of 519
Problem 1
A rectangular garden has an area of 269,361 square feet. If one of its dimensions is 519 feet, what is the other dimension?
The area of a rectangle = length × width
Here, the area is 269,361 square feet, and one dimension is 519 feet.
So, the other dimension = 269,361 ÷ 519 = 519 feet.
The other dimension is 519 feet.
Explanation
The area of the rectangular garden is 269,361 square feet.
With one dimension being 519 feet, the other dimension is 269,361 ÷ 519 = 519 feet.
Problem 2
A painter is painting a square ceiling with a side length of 519 feet. The cost to paint a square foot is 2 dollars. How much will it cost to paint the entire ceiling?
The side length of the ceiling = 519 feet
The cost to paint 1 square foot of ceiling = 2 dollars.
To find the total cost to paint, we find the area of the ceiling,
Area of the ceiling = side² Here, side = 519
Therefore, the area of the ceiling = 519² = 519 × 519 = 269,361.
The cost to paint the ceiling = 269,361 × 2 = 538,722.
The total cost = 538,722 dollars
Explanation
To find the cost to paint the ceiling, we multiply the area of the ceiling by the cost to paint per square foot.
So, the total cost is 538,722 dollars.
Problem 3
Find the area of a circle with a diameter of 519 meters.
The area of the circle = 211,130.87 m²
Explanation
The area of a circle = πr²
The radius r = diameter/2 = 519/2 = 259.5 meters
Therefore, the area of the circle = π × (259.5)² = 3.14 × 259.5 × 259.5 = 211,130.87 m².
Problem 4
The area of a square is 269,361 cm². What is the perimeter of the square?
The perimeter of the square is 2,076 cm.
Explanation
The area of the square = side²
Here, the area is 269,361 cm².
The length of the side is √269,361 = 519 cm.
Perimeter of the square = 4 × side
Here, side = 519 cm
Therefore, the perimeter = 4 × 519 = 2,076 cm.
Problem 5
Find the square of 520.
The square of 520 is 270,400.
Explanation
The square of 520 is multiplying 520 by 520.
So, the square = 520 × 520 = 270,400.
