Problem 1

Find the length of the square, where the area of the square is 182,329 cm².

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

The area of a square = a²

 

So, the area of a square = 182,329 cm²

 

So, the length = √182,329 = 427.

 

The length of each side = 427 cm

Explanation

The length of a square is 427 cm.

 

Because the area is 182,329 cm² the length is √182,329 = 427.

Problem 2

Alex is planning to paint his square wall of length 427 feet. The cost to paint a foot is 3 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 = 427 feet

 

The cost to paint 1 square foot of wall = 3 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 = 427 Therefore, the area of the wall = 427² = 427 × 427 = 182,329.

 

The cost to paint the wall = 182,329 × 3 = 546,987.

 

The total cost = 546,987 dollars

Explanation

To find the cost to paint the wall, we multiply the area of the wall by cost to paint per foot. So, the total cost is 546,987 dollars.

Problem 3

Find the area of a circle whose radius is 427 meters.

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

The area of the circle = 572,400.74 m²

Explanation

The area of a circle = πr²

 

Here, r = 427

 

Therefore, the area of the circle = π × 427² = 3.14 × 427 × 427 = 572,400.74 m².

Problem 4

The area of the square is 182,329 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 182,329 cm²

 

The length of the side is √182,329 = 427

 

Perimeter of the square = 4a

 

Here, a = 427

 

Therefore, the perimeter = 4 × 427 = 1,708.
