What is the Square of 0.25

The square of a number is the product of the number with itself. The square of 0.25 is 0.25 × 0.25. The square of a number can end in various digits. We write it in math as (0.252), where 0.25 is the base and 2 is the exponent. The square of a positive or negative number is always positive. For example, (0.52 = 0.25); ((-0.5)2 = 0.25)

 

The square of 0.25 is (0.25 × 0.25 = 0.0625).

 

Square of 0.25 in exponential form: (0.252)

 

Square of 0.25 in arithmetic form: 0.25 × 0.25

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 0.25.

 

Step 1: Identify the number. Here, the number is 0.25.

 

Step 2: Multiplying the number by itself, we get: 0.25 × 0.25 = 0.0625.

 

The square of 0.25 is 0.0625.

Professor Greenline from BrightChamps

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 0.25. So: (0.252 = 0.25 × 0.25 = 0.0625).

Problem 1

Find the length of a square, where the area of the square is 0.0625 cm².

Ray, the Boy Character from BrightChamps Saying "Let’s Begin"

The area of a square = (a2)

 

So, the area of a square = 0.0625 cm²

 

So, the length = √0.0625 = 0.25.

 

The length of each side = 0.25 cm

Explanation

The length of a square is 0.25 cm. Because the area is 0.0625 cm², the length is √0.0625 = 0.25.

Problem 2

Sarah is planning to paint a square tile of length 0.25 meters. The cost to paint a square meter is 20 dollars. Then how much will it cost to paint the full tile?

Ray, the Boy Character from BrightChamps Saying "Let’s Begin"

The length of the tile = 0.25 meters

 

The cost to paint 1 square meter = 20 dollars.

 

To find the total cost to paint, we find the area of the tile,

 

Area of the tile = area of the square = (a2)

 

Here (a = 0.25)

 

Therefore, the area of the tile = (0.252 = 0.25 × 0.25 = 0.0625)

 

The cost to paint the tile = 0.0625 × 20 = 1.25.

 

The total cost = 1.25 dollars

Explanation

To find the cost to paint the tile, we multiply the area of the tile by the cost to paint per square meter. So, the total cost is 1.25 dollars.

Problem 3

Find the area of a circle whose radius is 0.25 meters.

Ray, the Boy Character from BrightChamps Saying "Let’s Begin"

The area of the circle = 0.1963 m²

Explanation

The area of a circle = πr²

 

Here, r = 0.25

 

Therefore, the area of the circle = π × (0.252) = 3.14 × 0.25 × 0.25 = 0.1963 m².

Problem 4

The area of a square is 0.0625 cm². Find the perimeter of the square.

Ray, the Boy Character from BrightChamps Saying "Let’s Begin"

The perimeter of the square is 1 cm.

Explanation

The area of the square = (a2)

 

Here, the area is 0.0625 cm²

 

The length of the side is √0.0625 = 0.25

 

Perimeter of the square = 4a

 

Here, a = 0.25

 

Therefore, the perimeter = 4 × 0.25 = 1 cm.

Problem 5

Find the square of 0.3.

Ray, the Boy Character from BrightChamps Saying "Let’s Begin"

The square of 0.3 is 0.09

Explanation

The square of 0.3 is multiplying 0.3 by 0.3. So, the square = 0.3 × 0.3 = 0.09
