Solved Examples on Square of 627
Problem 1
Find the length of a square, where the area of the square is 393129 cm².
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?
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.
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.
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.
Problem 5
Find the square of 628.
The square of 628 is 394384
Explanation
The square of 628 is multiplying 628 by 628. So, the square = 628 × 628 = 394384
