Solved Examples on Square of 549
Problem 1
Find the length of the square, where the area of the square is 301,401 cm².
The area of a square = a²
So, the area of a square = 301,401 cm²
So, the length = √301,401 = 549.
The length of each side = 549 cm
Explanation
The length of a square is 549 cm. Because the area is 301,401 cm² the length is √301,401 = 549.
Problem 2
Anna wants to install tiles on her square floor of length 549 feet. The cost to install tiles per square foot is 5 dollars. Then how much will it cost to tile the full floor?
The length of the floor = 549 feet
The cost to install tiles per square foot = 5 dollars.
To find the total cost to install tiles, we find the area of the floor, Area of the floor = area of the square = a²
Here a = 549
Therefore, the area of the floor = 549² = 549 × 549 = 301,401.
The cost to install tiles = 301,401 × 5 = 1,507,005.
The total cost = 1,507,005 dollars
Explanation
To find the cost to install tiles, we multiply the area of the floor by the cost to install per square foot. So, the total cost is 1,507,005 dollars.
Problem 3
Find the area of a circle whose radius is 549 meters.
The area of the circle = 946,725.51 m²
Explanation
The area of a circle = πr²
Here, r = 549
Therefore, the area of the circle = π × 549² = 3.14 × 549 × 549 = 946,725.51 m².
Problem 4
The area of the square is 301,401 cm². Find the perimeter of the square.
The perimeter of the square is 2,196 cm.
Explanation
The area of the square = a²
Here, the area is 301,401 cm²
The length of the side is √301,401 = 549
Perimeter of the square = 4a
Here, a = 549
Therefore, the perimeter = 4 × 549 = 2,196.
Problem 5
Find the square of 550.
The square of 550 is 302,500.
Explanation
The square of 550 is multiplying 550 by 550.
So, the square = 550 × 550 = 302,500.
