By the Multiplication method
In this method, we will multiply the number by itself to find the square. The product here is the square of the number. Let’s find the square of 199.
Step 1: Identify the number. Here, the number is 199.
Step 2: Multiplying the number by itself, we get, 199 × 199 = 39601.
The square of 199 is 39601.
Using a Formula (a²)
In this method, the formula, a² is used to find the square of the number. Where a is the number.
Step 1: Understanding the equation Square of a number = a² a² = a × a
Step 2: Identifying the number and substituting the value in the equation.
Here, ‘a’ is 199.
So: 199² = 199 × 199 = 39601
By Using a Calculator
Using a calculator to find the square of a number is the easiest method. Let’s learn how to use a calculator to find the square of 199.
Step 1: Enter the number in the calculator. Enter 199 in the calculator.
Step 2: Multiply the number by itself using the multiplication button (×). That is 199 × 199
Step 3: Press the equal to button to find the answer.
Here, the square of 199 is 39601.
Tips and Tricks for the Square of 199
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 199
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 199² with (1+9+9)² or (100+99)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 199
Problem 1
A homeowner wants to tile a square floor with an area of 39601 square feet. What is the length of one side of the floor?
The area of a square = a² So, the area of a square = 39601 square feet So, the length = √39601 = 199. The length of each side = 199 feet
Explanation
The length of a square floor is 199 feet.
Because the area is 39601 square feet the length is √39601 = 199.
Problem 2
A company is building a square garden with each side measuring 199 meters. The maintenance cost is 2 dollars per square meter. What will be the total maintenance cost for the garden?
The length of the garden = 199 meters The cost to maintain 1 square meter of the garden = 2 dollars. To find the total cost to maintain, we find the area of the garden, Area of the garden = area of the square = a² Here a = 199 Therefore, the area of the garden = 199² = 199 × 199 = 39601. The cost to maintain the garden = 39601 × 2 = 79202. The total cost = 79202 dollars
Explanation
To find the cost to maintain the garden, we multiply the area of the garden by the cost to maintain per square meter.
So, the total cost is 79202 dollars.
Problem 3
Find the area of a circle whose radius is 199 meters.
The area of the circle = 124,529.94 m²
Explanation
The area of a circle = πr²
Here, r = 199
Therefore, the area of the circle = π × 199² = 3.14 × 199 × 199 = 124,529.94 m².
Problem 4
The area of the square is 39601 cm². Find the perimeter of the square.
The perimeter of the square is
Explanation
The area of the square = a²
Here, the area is 39601 cm²
The length of the side is √39601 = 199
Perimeter of the square = 4a
Here, a = 199
Therefore, the perimeter = 4 × 199 = 796.
Problem 5
Find the square of 200.
The square of 200 is 40000
Explanation
The square of 200 is multiplying 200 by 200.
So, the square = 200 × 200 = 40000
