Tips and Tricks for the Square of 1369
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 1369
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 by swapping 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 when using the formula.
The formula to find the square of the number is a². Instead, students may use 1369² with (13 + 69)² or (1300 + 69)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 do the operations in the correct order to avoid error.
Mistake 5
Not practicing regularly.
Regular practice is required to master the square of a number.
So students should do regular practice to avoid errors.
Solved Examples on Square of 1369
Problem 1
Find the side length of a square garden where the area is 1,876,161 square meters.
The area of a square = a²
So, the area of the square = 1,876,161 square meters
So, the side length = √1,876,161 = 1369.
The length of each side = 1369 meters
Explanation
The side length of the square garden is 1369 meters.
Because the area is 1,876,161 square meters, the length is √1,876,161 = 1369.
Problem 2
A square-shaped billboard has a side length of 1369 feet. If the cost to put up advertisements is 2 dollars per square foot, how much will it cost to cover the entire billboard?
The length of the billboard = 1369 feet
The cost to put up advertisement per square foot = 2 dollars.
To find the total cost, we find the area of the billboard.
Area of the billboard = area of the square = a²
Here a = 1369
Therefore, the area of the billboard = 1369² = 1369 × 1369 = 1,876,161.
The cost to cover the billboard = 1,876,161 × 2 = 3,752,322.
The total cost = 3,752,322 dollars
Explanation
To find the cost to cover the billboard, we multiply the area of the billboard by the cost per square foot.
So, the total cost is 3,752,322 dollars.
Problem 3
Find the area of a circle whose radius is 1369 meters.
The area of the circle = 5,897,267.06 m²
Explanation
The area of a circle = πr²
Here, r = 1369
Therefore, the area of the circle = π × 1369² = 3.14 × 1369 × 1369 = 5,897,267.06 m².
Problem 4
The area of a square is 1,876,161 square feet. Find the perimeter of the square.
The perimeter of the square is 5,476 feet.
Explanation
The area of the square = a²
Here, the area is 1,876,161 square feet
The length of the side is √1,876,161 = 1369
Perimeter of the square = 4a
Here, a = 1369
Therefore, the perimeter = 4 × 1369 = 5,476.
Problem 5
Find the square of 1370.
The square of 1370 is 1,876,900
Explanation
The square of 1370 is multiplying 1370 by 1370.
So, the square = 1370 × 1370 = 1,876,900
