Problem 1

Find the length of a square, where the area of the square is 667,489 cm².

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

The area of a square = a² So, the area of a square = 667,489 cm² So, the length = √667,489 = 817. The length of each side = 817 cm

Explanation

The length of a square is 817 cm because the area is 667,489 cm².

The length is √667,489 = 817.

Problem 2

Sarah is planning to tile her square courtyard of length 817 feet. The cost to tile a foot is 5 dollars. How much will it cost to tile the entire courtyard?

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

The length of the courtyard = 817 feet The cost to tile 1 square foot = 5 dollars. To find the total cost to tile, calculate the area of the courtyard, Area = a² Here a = 817 Therefore, the area = 817² = 817 × 817 = 667,489. The cost to tile the courtyard = 667,489 × 5 = 3,337,445. The total cost = 3,337,445 dollars

Explanation

To find the cost to tile the courtyard, multiply the area by the cost per foot.

The total cost is 3,337,445 dollars.

Problem 3

Find the area of a circle whose radius is 817 meters.

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

The area of the circle = 2,096,502.85 m²

Explanation

The area of a circle = πr²

Here, r = 817

Therefore, the area of the circle = π × 817² = 3.14 × 817 × 817 = 2,096,502.85 m².

Problem 4

The area of the square is 667,489 cm². Find the perimeter of the square.

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

The perimeter of the square is 3,268 cm.

Explanation

The area of the square = a²

Here, the area is 667,489 cm²

The length of the side is √667,489 = 817

Perimeter of the square = 4a

Here, a = 817

Therefore, the perimeter = 4 × 817 = 3,268 cm.
