Step 2: Multiply the number by itself using the multiplication button (×) That is 189 × 189
Step 3: Press the equal to button to find the answer Here, the square of 189 is 35721.
Tips and Tricks for the Square of 189
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 189
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 will be using the formula.
The formula to find the square of the number is a². Instead, students may use 189² with (1 + 8 + 9)² or (180 + 9)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 189
Problem 1
Find the length of the square, where the area of the square is 35721 cm².
The area of a square = a² So, the area of a square = 35721 cm² So, the length = √35721 = 189. The length of each side = 189 cm
Explanation
The length of a square is 189 cm.
Because the area is 35721 cm² the length is √35721 = 189.
Problem 2
Sarah is planning to tile her square garden of length 189 meters. The cost to tile a meter is 5 dollars. Then how much will it cost to tile the full garden?
The length of the garden = 189 meters
The cost to tile 1 square meter of the garden = 5 dollars.
To find the total cost to tile, we find the area of the garden,
Area of the garden = area of the square = a²
Here a = 189
Therefore, the area of the garden = 189² = 189 × 189 = 35721.
The cost to tile the garden = 35721 × 5 = 178605.
The total cost = 178605 dollars
Explanation
To find the cost to tile the garden, we multiply the area of the garden by the cost to tile per meter.
So, the total cost is 178605 dollars.
Problem 3
Find the area of a circle whose radius is 189 meters.
The area of the circle = 112,711.86 m²
Explanation
The area of a circle = πr² Here, r = 189
Therefore, the area of the circle = π × 189² = 3.14 × 189 × 189 = 112,711.86 m².
Problem 4
The area of the square is 35721 cm². Find the perimeter of the square.
The perimeter of the square is 756 cm
Explanation
The area of the square = a²
Here, the area is 35721 cm²
The length of the side is √35721 = 189
Perimeter of the square = 4a Here, a = 189
Therefore, the perimeter = 4 × 189 = 756.
Problem 5
Find the square of 190.
The square of 190 is 36100
Explanation
The square of 190 is multiplying 190 by 190.
So, the square = 190 × 190 = 36100
