Problem 1

Find the length of the square, where the area of the square is 308025 cm².

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

The area of a square = a²

So, the area of a square = 308025 cm²

So, the length = √308025 = 555.

The length of each side = 555 cm

Explanation

The length of a square is 555 cm.

Because the area is 308025 cm², the length is √308025 = 555.

Problem 2

Jane is planning to paint her square wall of length 555 feet. The cost to paint a foot is 2 dollars. Then how much will it cost to paint the full wall?

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

The length of the wall = 555 feet

The cost to paint 1 square foot of wall = 2 dollars.

To find the total cost to paint, we find the area of the wall, Area of the wall = area of the square = a²

Here a = 555

Therefore, the area of the wall = 555² = 555 × 555 = 308025.

The cost to paint the wall = 308025 × 2 = 616050.

The total cost = 616050 dollars

Explanation

To find the cost to paint the wall, we multiply the area of the wall by the cost to paint per foot.

So, the total cost is 616050 dollars.

Problem 3

Find the area of a circle whose radius is 555 meters.

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

The area of the circle = 967,467.3 m²

Explanation

The area of a circle = πr²

Here, r = 555

Therefore, the area of the circle = π × 555² = 3.14 × 555 × 555 = 967,467.3 m².

Problem 4

The area of the square is 308025 cm². Find the perimeter of the square.

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

The perimeter of the square is

Explanation

The area of the square = a²

Here, the area is 308025 cm²

The length of the side is √308025 = 555

Perimeter of the square = 4a

Here, a = 555

Therefore, the perimeter = 4 × 555 = 2220.
