Solved Examples on Square of 626
Problem 1
Find the length of the square, where the area of the square is 391876 cm².
The area of a square = a²
So, the area of a square = 391876 cm²
So, the length = √391876 = 626.
The length of each side = 626 cm
Explanation
The length of a square is 626 cm.
Because the area is 391876 cm², the length is √391876 = 626.
Problem 2
Sarah is planning to carpet her square room of length 626 feet. The cost to carpet a foot is 3 dollars. Then how much will it cost to carpet the full room?
The length of the room = 626 feet
The cost to carpet 1 square foot of the room = 3 dollars.
To find the total cost to carpet, we find the area of the room,
Area of the room = area of the square = a²
Here a = 626
Therefore, the area of the room = 626² = 626 × 626 = 391876.
The cost to carpet the room = 391876 × 3 = 1175628.
The total cost = 1175628 dollars
Explanation
To find the cost to carpet the room, we multiply the area of the room by the cost to carpet per foot. So, the total cost is 1175628 dollars.
Problem 3
Find the area of a circle whose radius is 626 meters.
The area of the circle = 1,230,296.96 m²
Explanation
The area of a circle = πr²
Here, r = 626
Therefore, the area of the circle = π × 626² = 3.14 × 626 × 626 = 1,230,296.96 m².
Problem 4
The area of the square is 391876 cm². Find the perimeter of the square.
The perimeter of the square is 2504 cm
Explanation
The area of the square = a²
Here, the area is 391876 cm²
The length of the side is √391876 = 626
Perimeter of the square = 4a
Here, a = 626
Therefore, the perimeter = 4 × 626 = 2504.
Problem 5
Find the square of 627.
The square of 627 is 393129
Explanation
The square of 627 is multiplying 627 by 627.
So, the square = 627 × 627 = 393129
