The product of multiplying an integer by itself is the square of a number. Squares are used in programming, calculating areas, and so on. In this topic, we will discuss the square of 121.
The square of a number is the product of the number itself.
The square of 121 is 121 × 121.
The square of a number always ends in 0, 1, 4, 5, 6, or 9.
We write it in math as 121², where 121 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 121 is 121 × 121 = 14641.
Square of 121 in exponential form: 121²
Square of 121 in arithmetic form: 121 × 121
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 121:
Step 1: Identify the number. Here, the number is 121.
Step 2: Multiplying the number by itself, we get, 121 × 121 = 14641.
The square of 121 is 14641.
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 121.
So: 121² = 121 × 121 = 14641
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 121.
Step 1: Enter the number in the calculator. Enter 121 in the calculator.
Step 2: Multiply the number by itself using the multiplication button (×). That is 121 × 121.
Step 3: Press the equal to button to find the answer. Here, the square of 121 is 14641.
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 the square, where the area of the square is 14641 cm².
The area of a square = a²
So, the area of a square = 14641 cm²
So, the length = √14641 = 121.
The length of each side = 121 cm
The length of a square is 121 cm. Because the area is 14641 cm² the length is √14641 = 121.
Sarah is planning to tile her square floor of length 121 feet. The cost to tile a foot is 5 dollars. How much will it cost to tile the full floor?
The length of the floor = 121 feet
The cost to tile 1 square foot of floor = 5 dollars.
To find the total cost to tile, we find the area of the floor,
Area of the floor = area of the square = a²
Here a = 121
Therefore, the area of the floor = 121² = 121 × 121 = 14641.
The cost to tile the floor = 14641 × 5 = 73205.
The total cost = 73205 dollars
To find the cost to tile the floor, we multiply the area of the floor by the cost to tile per foot. So, the total cost is 73205 dollars.
Find the area of a circle whose radius is 121 meters.
The area of the circle = 45931.5 m²
The area of a circle = πr²
Here, r = 121
Therefore, the area of the circle = π × 121² = 3.14 × 121 × 121 = 45931.5 m².
The area of the square is 14641 cm². Find the perimeter of the square.
The perimeter of the square is 484 cm.
The area of the square = a²
Here, the area is 14641 cm²
The length of the side is √14641 = 121
Perimeter of the square = 4a
Here, a = 121
Therefore, the perimeter = 4 × 121 = 484.
Find the square of 122.
The square of 122 is 14884.
The square of 122 is multiplying 122 by 122.
So, the square = 122 × 122 = 14884.
