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 1245.
The square of a number is the product of the number itself.
The square of 1245 is 1245 × 1245.
The square of a number always ends in 0, 1, 4, 5, 6, or 9.
We write it in math as 1245², where 1245 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 1245 is 1245 × 1245 = 1,550,025.
Square of 1245 in exponential form: 1245²
Square of 1245 in arithmetic form: 1245 × 1245
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 1245.
Step 1: Identify the number. Here, the number is 1245.
Step 2: Multiplying the number by itself, we get, 1245 × 1245 = 1,550,025.
The square of 1245 is 1,550,025.
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 1245.
So: 1245² = 1245 × 1245 = 1,550,025
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 1245.
Step 1: Enter the number in the calculator. Enter 1245 in the calculator.
Step 2: Multiply the number by itself using the multiplication button (×). That is 1245 × 1245
Step 3: Press the equal to button to find the answer. Here, the square of 1245 is 1,550,025.
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.
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 a square, where the area of the square is 1,550,025 cm².
The area of a square = a²
So, the area of a square = 1,550,025 cm²
So, the length = √1,550,025 = 1245.
The length of each side = 1245 cm
The length of a square is 1245 cm.
Because the area is 1,550,025 cm², the length is √1,550,025 = 1245.
Sarah is planning to tile her square patio of length 1245 feet. The cost to tile a foot is 6 dollars. Then how much will it cost to tile the full patio?
The length of the patio = 1245 feet
The cost to tile 1 square foot of patio = 6 dollars.
To find the total cost to tile, we find the area of the patio.
Area of the patio = area of the square = a²
Here a = 1245
Therefore, the area of the patio = 1245² = 1245 × 1245 = 1,550,025.
The cost to tile the patio = 1,550,025 × 6 = 9,300,150.
The total cost = 9,300,150 dollars
To find the cost to tile the patio, we multiply the area of the patio by the cost to tile per foot. So, the total cost is 9,300,150 dollars.
Find the area of a circle whose radius is 1245 meters.
The area of the circle = 4,869,291.75 m²
The area of a circle = πr²
Here, r = 1245
Therefore, the area of the circle = π × 1245² = 3.14 × 1245 × 1245 = 4,869,291.75 m².
The area of a square is 1,550,025 cm². Find the perimeter of the square.
The perimeter of the square is 4,980 cm.
The area of the square = a²
Here, the area is 1,550,025 cm²
The length of the side is √1,550,025 = 1245
Perimeter of the square = 4a
Here, a = 1245
Therefore, the perimeter = 4 × 1245 = 4,980.
Find the square of 1246.
The square of 1246 is 1,552,516.
The square of 1246 is multiplying 1246 by 1246.
So, the square = 1246 × 1246 = 1,552,516.
