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 0.05 So: 0.05² = 0.05 × 0.05 = 0.0025

Solved Examples on Square of 0.05

Ray, the Character from BrightChamps Explaining Math Concepts

Problem 1

Find the length of a side of a square if the area of the square is 0.0025 m².

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

The area of a square = a²

 

So, the area of the square = 0.0025 m²

 

Thus, the length = √0.0025 = 0.05.

 

The length of each side = 0.05 m

Explanation

The length of a square is 0.05 m.

 

Because the area is 0.0025 m², the length is √0.0025 = 0.05.

Problem 2

A landscaper is laying tiles each measuring 0.05 m on a square plot of land. Each tile costs $2. How much will it cost to cover an area of 0.0025 m²?

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

The length of the tile = 0.05 m

 

The cost to lay one tile = $2

 

To find the total cost, we find the area of the plot,

 

Area of the plot = area of the square = a²

 

Here a = 0.05

 

Therefore, the area of the plot = 0.05² = 0.05 × 0.05 = 0.0025.

 

The cost to cover the plot = 0.0025 × 2 = $0.005 The total cost = $0.005

Explanation

To find the cost to cover the plot, we multiply the area by the cost per unit area. So, the total cost is $0.005.

Problem 3

Find the area of a circle whose radius is 0.05 m.

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

The area of the circle = 0.00785 m²

Explanation

The area of a circle = πr²

 

Here, r = 0.05

 

Therefore, the area of the circle = π × 0.05² = 3.14 × 0.05 × 0.05 = 0.00785 m².

Problem 4

The area of a square is 0.0025 m². Find the perimeter of the square.

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

The perimeter of the square is 0.2 m

Explanation

The area of the square = a²

 

Here, the area is 0.0025 m²

 

The length of the side is √0.0025 = 0.05

 

Perimeter of the square = 4a

 

Here, a = 0.05

 

Therefore, the perimeter = 4 × 0.05 = 0.2.

Problem 5

Find the square of 0.06.

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

The square of 0.06 is 0.0036

Explanation

The square of 0.06 is multiplying 0.06 by 0.06. So, the square = 0.06 × 0.06 = 0.0036
