Common Mistakes to Avoid When Calculating the Square of 303

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 length of the square, where the area of the square is 91,809 cm².

Okay, lets begin

The area of a square = a²

So, the area of a square = 91,809 cm²

So, the length = √91,809 = 303.

The length of each side = 303 cm

Explanation

The length of a square is 303 cm. Because the area is 91,809 cm² the length is √91,809 = 303.

Problem 2

Alice wants to fence her square garden of length 303 feet. The cost to fence a foot is 5 dollars. Then how much will it cost to fence the entire garden?

Okay, lets begin

The length of the garden = 303 feet

The cost to fence 1 foot of the garden = 5 dollars.

To find the total cost to fence, we find the perimeter of the garden, Perimeter of the garden = 4a

Here a = 303

Therefore, the perimeter = 4 × 303 = 1,212.

The cost to fence the garden = 1,212 × 5 = 6,060 dollars.

The total cost = 6,060 dollars

Explanation

To find the cost to fence the garden, we multiply the perimeter of the garden by the cost to fence per foot. So, the total cost is 6,060 dollars.

Problem 3

Find the area of a circle whose radius is 303 meters.

Okay, lets begin

The area of the circle = 288,256.74 m²

Explanation

The area of a circle = πr²

Here, r = 303

Therefore, the area of the circle = π × 303² = 3.14 × 303 × 303 = 288,256.74 m².

Problem 4

The area of the square is 92,000 cm². Find the perimeter of the square.

Okay, lets begin

The perimeter of the square is

Explanation

The area of the square = a²

Here, the area is 92,000 cm²

The length of the side is √92,000 ≈ 303.32

Perimeter of the square = 4a

Here, a ≈ 303.32

Therefore, the perimeter = 4 × 303.32 ≈ 1,213.28.
