Solved Examples on Square of 2209
Problem 1
Find the length of the square, where the area of the square is 4884121 cm².
The area of a square = a²
So, the area of a square = 4884121 cm²
So, the length = √4884121 = 2209.
The length of each side = 2209 cm
Explanation
The length of a square is 2209 cm.
Because the area is 4884121 cm² the length is √4884121 = 2209.
Problem 2
Sarah is planning to paint her square wall of length 2209 feet. The cost to paint a foot is 3 dollars. Then how much will it cost to paint the full wall?
The length of the wall = 2209 feet
The cost to paint 1 square foot of wall = 3 dollars.
To find the total cost to paint, we find the area of the wall,
Area of the wall = area of the square = a²
Here a = 2209
Therefore, the area of the wall = 2209² = 2209 × 2209 = 4884121.
The cost to paint the wall = 4884121 × 3 = 14652363.
The total cost = 14652363 dollars
Explanation
To find the cost to paint the wall, we multiply the area of the wall by cost to paint per foot. So, the total cost is 14652363 dollars.
Problem 3
Find the area of a circle whose radius is 2209 meters.
The area of the circle = 15335125.66 m²
Explanation
The area of a circle = πr²
Here, r = 2209
Therefore, the area of the circle = π × 2209² = 3.14 × 2209 × 2209 = 15335125.66 m².
Problem 4
The area of the square is 4884121 cm². Find the perimeter of the square.
The perimeter of the square is 8836 cm
Explanation
The area of the square = a²
Here, the area is 4884121 cm²
The length of the side is √4884121 = 2209
Perimeter of the square = 4a
Here, a = 2209
Therefore, the perimeter = 4 × 2209 = 8836 cm.
Problem 5
Find the square of 2210.
The square of 2210 is 4884100
Explanation
The square of 2210 is multiplying 2210 by 2210.
So, the square = 2210 × 2210 = 4884100
