Solved Examples on Square of 628
Problem 1
Find the length of the square, where the area of the square is 394,384 cm².
The area of a square = a²
So, the area of a square = 394,384 cm²
So, the length = √394,384 = 628.
The length of each side = 628 cm
Explanation
The length of a square is 628 cm.
Because the area is 394,384 cm², the length is √394,384 = 628.
Problem 2
Sarah is tiling her square floor, which has a length of 628 feet. The cost to tile a foot is 5 dollars. How much will it cost to tile the full floor?
The length of the floor = 628 feet
The cost to tile 1 square foot of floor = 5 dollars.
To find the total cost to tile, we find the area of the floor,
Area of the floor = area of the square = a²
Here a = 628
Therefore, the area of the floor = 628² = 628 × 628 = 394,384.
The cost to tile the floor = 394,384 × 5 = 1,971,920.
The total cost = 1,971,920 dollars
Explanation
To find the cost to tile the floor, we multiply the area of the floor by the cost to tile per foot. So, the total cost is 1,971,920 dollars.
Problem 3
Find the area of a circle whose radius is 628 meters.
The area of the circle = 1,239,267.91 m²
Explanation
The area of a circle = πr²
Here, r = 628
Therefore, the area of the circle = π × 628² = 3.14 × 628 × 628 = 1,239,267.91 m².
Problem 4
The area of the square is 394,384 cm². Find the perimeter of the square.
The perimeter of the square is 2,512 cm
Explanation
The area of the square = a²
Here, the area is 394,384 cm²
The length of the side is √394,384 = 628
Perimeter of the square = 4a
Here, a = 628
Therefore, the perimeter = 4 × 628 = 2,512.
Problem 5
Find the square of 629.
The square of 629 is 395,641
Explanation
The square of 629 is multiplying 629 by 629.
So, the square = 629 × 629 = 395,641
