Common Mistakes to Avoid When Calculating the Square of 5.6

Mistakes are common among kids 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 the square, where the area of the square is 31.36 cm².

Okay, lets begin

The area of a square = a²

So, the area of a square = 31.36 cm²

So, the length = √31.36

= 5.6

The length of each side = 5.6 cm

Explanation

The length of a square is 5.6 cm.

Because the area is 31.36 cm² the length is √31.36 = 5.6.

Problem 2

Sara is planning to tile her square garden of length 5.6 meters. The cost to tile a square meter is 20 dollars. Then how much will it cost to tile the entire garden?

Okay, lets begin

The length of the garden = 5.6 meters

The cost to tile 1 square meter of the garden = 20 dollars.

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

Area of the garden = area of the square

= a² Here a = 5.6

Therefore, the area of the garden = 5.6² = 5.6 × 5.6 = 31.36.

The cost to tile the garden = 31.36 × 20 = 627.2

The total cost = 627.2 dollars

Explanation

To find the cost to tile the garden, we multiply the area of the garden by the cost to tile per square meter. So, the total cost is 627.2 dollars.

Problem 3

Find the area of a circle whose radius is 5.6 meters.

Okay, lets begin

The area of the circle = 98.54 m²

Explanation

The area of a circle = πr²

Here, r = 5.6

Therefore, the area of the circle = π × 5.6²

= 3.14 × 5.6 × 5.6

= 98.54 m².

Problem 4

The area of the square is 31.36 cm². Find the perimeter of the square.

Okay, lets begin

The perimeter of the square is 22.4 cm.

Explanation

The area of the square = a²

Here, the area is 31.36 cm²

The length of the side is √31.36 = 5.6

Perimeter of the square = 4a

Here, a = 5.6

Therefore, the perimeter = 4 × 5.6 = 22.4.

Problem 5

Find the square of 6.3.

Okay, lets begin

The square of 6.3 is 39.69

Explanation

The square of 6.3 is multiplying 6.3 by 6.3.

So, the square = 6.3 × 6.3 = 39.69
