Solved Examples on Square of 1128
Problem 1
Find the length of the square, where the area of the square is 1,272,384 cm².
The area of a square = a² So, the area of a square = 1,272,384 cm² So, the length = √1,272,384 = 1128. The length of each side = 1128 cm
Explanation
The length of a square is 1128 cm.
Because the area is 1,272,384 cm², the length is √1,272,384 = 1128.
Problem 2
Sarah wants to lay tiles on her square courtyard of length 1128 feet. The cost to lay a tile per square foot is 5 dollars. How much will it cost to tile the entire courtyard?
The length of the courtyard = 1128 feet The cost to lay 1 square foot of tile = 5 dollars. To find the total cost to tile, we find the area of the courtyard, Area of the courtyard = area of the square = a² Here a = 1128 Therefore, the area of the courtyard = 1128² = 1128 × 1128 = 1,272,384. The cost to tile the courtyard = 1,272,384 × 5 = 6,361,920. The total cost = 6,361,920 dollars
Explanation
To find the cost to tile the courtyard, we multiply the area of the courtyard by the cost to lay per foot.
So, the total cost is 6,361,920 dollars.
Problem 3
Find the area of a circle whose radius is 1128 meters.
The area of the circle = 3,994,141.44 m²
Explanation
The area of a circle = πr²
Here, r = 1128
Therefore, the area of the circle = π × 1128² = 3.14 × 1128 × 1128 = 3,994,141.44 m².
Problem 4
The area of the square is 1,272,384 cm². Find the perimeter of the square.
The perimeter of the square is
Explanation
The area of the square = a²
Here, the area is 1,272,384 cm²
The length of the side is √1,272,384 = 1128
Perimeter of the square = 4a
Here, a = 1128
Therefore, the perimeter = 4 × 1128 = 4512.
Problem 5
Find the square of 1129.
The square of 1129 is 1,274,641
Explanation
The square of 1129 is multiplying 1129 by 1129.
So, the square = 1129 × 1129 = 1,274,641
