Solved Examples on Square of 627

Ray, the Character from BrightChamps Explaining Math Concepts
Max, the Girl Character from BrightChamps

Problem 1

Find the length of a square, where the area of the square is 393129 cm².

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

The area of a square = a²

 

So, the area of a square = 393129 cm²

 

So, the length = √393129 = 627.

 

The length of each side = 627 cm

Explanation

The length of a square is 627 cm.

 

Because the area is 393129 cm², the length is √393129 = 627.

Problem 2

Sarah wants to carpet her square room of length 627 feet. The cost to carpet a foot is 10 dollars. How much will it cost to carpet the full room?

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

The length of the room = 627 feet

 

The cost to carpet 1 square foot of the room = 10 dollars.

 

To find the total cost to carpet, find the area of the room,

 

Area of the room = area of the square = a²

 

Here a = 627

 

Therefore, the area of the room = 627² = 627 × 627 = 393129.

 

The cost to carpet the room = 393129 × 10 = 3931290.

 

The total cost = 3931290 dollars

Explanation

To find the cost to carpet the room, multiply the area of the room by the cost to carpet per foot. So, the total cost is 3931290 dollars.

Problem 3

Find the area of a circle whose radius is 627 meters.

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

The area of the circle = 1,236,605.22 m²

Explanation

The area of a circle = πr²

 

Here, r = 627

 

Therefore, the area of the circle = π × 627² = 3.14 × 627 × 627 = 1,236,605.22 m².

Problem 4

The area of the square is 400000 cm². Find the perimeter of the square.

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

The perimeter of the square is 2520 cm.

Explanation

The area of the square = a²

 

Here, the area is 400000 cm²

 

The length of the side is √400000 = 632

 

Perimeter of the square = 4a

 

Here, a = 632

 

Therefore, the perimeter = 4 × 632 = 2528.
