Using a Formula (a²)

In this method, the formula a² is used to find the square of a number, where a is the number.

 

Step 1: Understanding the equation Square of a number = a² a² = a × a

 

Step 2: Identify the number and substitute the value in the equation.

 

Here, ‘a’ is 831.

 

So: 831² = 831 × 831 = 690,561

Problem 1

Find the length of the square, where the area of the square is 690,561 cm².

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

The area of a square = a² So, the area of a square = 690,561 cm² So, the length = √690,561 = 831. The length of each side = 831 cm.

Explanation

The length of a square is 831 cm.

Because the area is 690,561 cm², the length is √690,561 = 831.

Problem 2

Sarah is planning to lay tiles on her square garden with a length of 831 feet. The cost to lay tiles per square foot is 5 dollars. How much will it cost to tile the full garden?

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

The length of the garden = 831 feet The cost to lay tiles per square foot = 5 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 = 831 Therefore, the area of the garden = 831² = 831 × 831 = 690,561. The cost to tile the garden = 690,561 × 5 = 3,452,805. The total cost = 3,452,805 dollars.

Explanation

To find the cost to tile the garden, we multiply the area of the garden by the cost to tile per foot.

So, the total cost is 3,452,805 dollars.

Problem 3

Find the area of a circle whose radius is 831 meters.

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

The area of the circle = 2,168,890.86 m²

Explanation

The area of a circle = πr²

Here, r = 831

Therefore, the area of the circle = π × 831² = 3.14 × 831 × 831 = 2,168,890.86 m².

Problem 4

The area of the square is 690,561 cm². Find the perimeter of the square.

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

The perimeter of the square is 3,324 cm.

Explanation

The area of the square = a²

Here, the area is 690,561 cm²

The length of the side is √690,561 = 831.

Perimeter of the square = 4a

Here, a = 831

Therefore, the perimeter = 4 × 831 = 3,324.
