The product of multiplying an integer by itself is the square of a number. Square is used in programming, calculating areas, and so on. In the topic, we will discuss the square of 69.
The square of a number is the product of the number itself.
The square of 69 is 69 × 69.
The square of a number always ends in 0, 1, 4, 5, 6, or 9.
We write it in math as 69², where 69 is the base and 2 is the exponent.
The square of a positive and a negative number is always positive. For example, 5² = 25; -5² = 25.
The square of 69 is 69 × 69 = 4761.
Square of 69 in exponential form: 69²
Square of 69 in arithmetic form: 69 × 69
The square of a number is multiplying the number by itself. So let’s learn how to find the square of a number. These are the common methods used to find the square of a number.
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 69.
Step 1: Identify the number. Here, the number is 69
Step 2: Multiplying the number by itself, we get, 69 × 69 = 4761.
The square of 69 is 4761.
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 69.
So: 69² = 69 × 69 = 4761
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 69.
Step 1: Enter the number in the calculator Enter 69 in the calculator.
Step 2: Multiply the number by itself using the multiplication button (×). That is 69 × 69
Step 3: Press the equal to button to find the answer Here, the square of 69 is 4761.
Tips and tricks make it easy for students to understand and learn the square of a number.
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.
Find the length of the square, where the area of the square is 4761 cm².
The area of a square = a²
So, the area of a square = 4761 cm²
So, the length = √4761 = 69.
The length of each side = 69 cm
The length of a square is 69 cm.
Because the area is 4761 cm² the length is √4761 = 69.
Sarah is planning to cover her square garden of length 69 meters with tiles. The cost to pave a square meter is 5 dollars. Then how much will it cost to pave the full garden?
The length of the garden = 69 meters
The cost to pave 1 square meter of garden = 5 dollars.
To find the total cost to pave, we find the area of the garden,
Area of the garden = area of the square = a²
Here a = 69
Therefore, the area of the garden = 69² = 69 × 69 = 4761.
The cost to pave the garden = 4761 × 5 = 23805.
The total cost = 23805 dollars
To find the cost to pave the garden, we multiply the area of the garden by cost to pave per meter. So, the total cost is 23805 dollars.
Find the area of a circle whose radius is 69 meters.
The area of the circle = 14,948.34 m²
The area of a circle = πr²
Here, r = 69
Therefore, the area of the circle = π × 69² = 3.14 × 69 × 69 = 14,948.34 m².
The area of the square is 4761 cm². Find the perimeter of the square.
The perimeter of the square is 276 cm
The area of the square = a²
Here, the area is 4761 cm²
The length of the side is √4761 = 69
Perimeter of the square = 4a
Here, a = 69 Therefore, the perimeter = 4 × 69 = 276.
Find the square of 70.
The square of 70 is 4900
The square of 70 is multiplying 70 by 70.
So, the square = 70 × 70 = 4900
