Common Mistakes to Avoid When Calculating the Square of 0.05

Mistakes are common when doing math, especially when finding the square of a number. Let’s learn some common mistakes to master the squaring of a number.

Problem 1

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

Okay, lets 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?

Okay, lets 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.

Okay, lets 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.

Well explained 👍

Problem 4

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

Okay, lets 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.

Well explained 👍

Problem 5

Find the square of 0.06.

Okay, lets 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
