Solved Examples on Square of 530
Problem 1
Find the length of the side of a square where the area of the square is 280,900 cm².
The area of a square = a²
So, the area of a square = 280,900 cm²
So, the length = √280,900 = 530.
The length of each side = 530 cm
Explanation
The length of a square is 530 cm. Because the area is 280,900 cm², the length is √280,900 = 530.
Problem 2
Jessica is planning to wallpaper her square room with sides of length 530 feet. The cost to wallpaper a square foot is 2.5 dollars. How much will it cost to wallpaper the entire room?
The length of the room = 530 feet The cost to wallpaper 1 square foot of the room = 2.5 dollars.
To find the total cost to wallpaper, we find the area of the room, Area of the room = area of the square = a²
Here a = 530
Therefore, the area of the room = 530² = 530 × 530 = 280,900.
The cost to wallpaper the room = 280,900 × 2.5 = 702,250.
The total cost = 702,250 dollars
Explanation
To find the cost to wallpaper the room, we multiply the area of the room by the cost to wallpaper per square foot. So, the total cost is 702,250 dollars.
Problem 3
Find the area of a circle whose radius is 530 meters.
The area of the circle = 882,340 m²
Explanation
The area of a circle = πr²
Here, r = 530
Therefore, the area of the circle = π × 530² = 3.14 × 530 × 530 = 882,340 m².
Problem 4
The area of the square is 280,900 cm². Find the perimeter of the square.
The perimeter of the square is 2,120 cm.
Explanation
The area of the square = a²
Here, the area is 280,900 cm²
The length of the side is √280,900 = 530
Perimeter of the square = 4a
Here, a = 530
Therefore, the perimeter = 4 × 530 = 2,120 cm.
Problem 5
Find the square of 531.
The square of 531 is 281,961.
Explanation
The square of 531 is multiplying 531 by 531.
So, the square = 531 × 531 = 281,961
