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 this topic, we will discuss the square of 29.
The square of a number is the product of the number by itself. The square of 29 is 29 × 29. The square of a number always ends in 0, 1, 4, 5, 6, or 9. We write it in math as 29², where 29 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 29 is 29 × 29 = 841.
Square of 29 in exponential form: 29²
Square of 29 in arithmetic form: 29 × 29
The square of a number is determined by multiplying the number by itself. Here are common methods used to find the square of a number:
In this method, we multiply the number by itself to find the square. The product here is the square of the number. Let’s find the square of 29.
Step 1: Identify the number. Here, the number is 29
Step 2: Multiplying the number by itself, we get, 29 × 29 = 841.
The square of 29 is 841.
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 29
So: 29² = 29 × 29 = 841

Tips and Tricks for the Square of 29
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 841 cm².
The area of a square = a²
So, the area of a square = 841 cm²
So, the length = √841 = 29.
The length of each side = 29 cm
The length of a square is 29 cm.
Because the area is 841 cm², the length is √841 = 29.
Lucy wants to carpet her square room of length 29 feet. The cost to carpet a square foot is 5 dollars. How much will it cost to carpet the entire room?
The length of the room = 29 feet
The cost to carpet 1 square foot of the room = 5 dollars.
To find the total cost to carpet, we find the area of the room,
Area of the room = area of the square = a²
Here a = 29
Therefore, the area of the room = 29² = 29 × 29 = 841.
The cost to carpet the room = 841 × 5 = 4205.
The total cost = 4205 dollars
To find the cost to carpet the room, we multiply the area of the room by the cost to carpet per foot. So, the total cost is 4205 dollars.
Find the area of a circle whose radius is 29 meters.
The area of the circle = 2,644.18 m²
The area of a circle = πr²
Here, r = 29
Therefore, the area of the circle = π × 29²
= 3.14 × 29 × 29
= 2644.18 m².
The area of the square is 961 cm². Find the perimeter of the square.
The perimeter of the square is
The area of the square = a²
Here, the area is 961 cm²
The length of the side is √961 = 31
Perimeter of the square = 4a
Here, a = 31
Therefore, the perimeter = 4 × 31 = 124.
Find the square of 30.
The square of 30 is 900
The square of 30 is multiplying 30 by 30.
So, the square = 30 × 30 = 900
