Solved Examples on Square of 619
Problem 1
Find the length of the square, where the area of the square is 383,161 cm².
The area of a square = a²
So, the area of a square = 383,161 cm²
So, the length = √383,161 = 619.
The length of each side = 619 cm
Explanation
The length of a square is 619 cm. Because the area is 383,161 cm² the length is √383,161 = 619.
Problem 2
Sarah is planning to cover her square garden of length 619 feet with tiles. Each tile covers an area of 1 square foot. How many tiles are needed to cover the full garden?
The length of the garden = 619 feet
To find the total number of tiles needed, we find the area of the garden,
Area of the garden = area of the square = a²
Here a = 619
Therefore, the area of the garden = 619² = 619 × 619 = 383,161.
The total number of tiles needed = 383,161.
Explanation
To find the number of tiles needed to cover the garden, we calculate the area of the garden. So, the total number of tiles is 383,161.
Problem 3
Find the area of a circle whose radius is 619 meters.
The area of the circle = 1,202,362.76 m²
Explanation
The area of a circle = πr²
Here, r = 619
Therefore, the area of the circle = π × 619² = 3.14 × 619 × 619 = 1,202,362.76 m².
Problem 4
The area of the square is 383,161 cm². Find the perimeter of the square.
The perimeter of the square is
Explanation
The area of the square = a²
Here, the area is 383,161 cm²
The length of the side is √383,161 = 619
Perimeter of the square = 4a
Here, a = 619
Therefore, the perimeter = 4 × 619 = 2,476.
Problem 5
Find the square of 620.
The square of 620 is 384,400
Explanation
The square of 620 is multiplying 620 by 620.
So, the square = 620 × 620 = 384,400
