Common Mistakes to Avoid When Calculating the Square of 1.6

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.

Problem 1

Find the area of a square plot where the side is 1.6 meters.

Okay, lets begin

The area of a square = a²

The side of the square = 1.6 meters

So, the area = 1.6² = 1.6 × 1.6 = 2.56 m²

Explanation

The area of the square is 2.56 m² because the side length of the square is 1.6 meters. Hence, the area is 1.6 × 1.6 = 2.56 m².

Problem 2

A square garden has a side length of 1.6 meters. If the cost to plant flowers is $5 per square meter, what is the total cost to plant the garden?

Okay, lets begin

The side of the garden = 1.6 meters

The cost to plant per square meter = $5

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

Area of the garden = area of the square = a²

Here a = 1.6

Therefore, the area of the garden = 1.6² = 1.6 × 1.6 = 2.56 m²

The cost to plant the garden = 2.56 × 5 = $12.80

The total cost = $12.80

Explanation

To find the cost to plant the garden, we multiply the area of the garden by the cost to plant per square meter. So, the total cost is $12.80.

Problem 3

Find the area of a circle whose radius is 1.6 meters.

Okay, lets begin

The area of the circle = 8.042 m²

Explanation

The area of a circle = πr²

Here, r = 1.6

Therefore, the area of the circle = π × 1.6² = 3.14 × 1.6 × 1.6 = 8.042 m².

Well explained 👍

Problem 4

The area of a square is 2.56 cm². Find the perimeter of the square.

Okay, lets begin

The perimeter of the square is 6.4 cm

Explanation

The area of the square = a²

Here, the area is 2.56 cm²

The length of the side is √2.56 = 1.6

Perimeter of the square = 4a

Here, a = 1.6

Therefore, the perimeter = 4 × 1.6 = 6.4 cm.

Well explained 👍

Problem 5

Find the square of 1.7.

Okay, lets begin

The square of 1.7 is 2.89

Explanation

The square of 1.7 is multiplying 1.7 by 1.7. So, the square = 1.7 × 1.7 = 2.89
