Solved Examples on Square of 239
Problem 1
Find the length of the square, where the area of the square is 57121 cm².
The area of a square = a² So, the area of a square = 57121 cm² So, the length = √57121 = 239. The length of each side = 239 cm
Explanation
The length of a square is 239 cm.
Because the area is 57121 cm² the length is √57121 = 239.
Problem 2
Alice is planning to paint her square mural of length 239 inches. The cost to paint an inch is 2 dollars. Then how much will it cost to paint the full mural?
The length of the mural = 239 inches The cost to paint 1 square inch of mural = is 2 dollars. To find the total cost to paint, we find the area of the mural, Area of the mural = area of the square = a² Here a = 239 Therefore, the area of the mural = 239² = 239 × 239 = 57121. The cost to paint the mural = 57121 × 2 = 114242. The total cost = 114242 dollars
Explanation
To find the cost to paint the mural, we multiply the area of the mural by the cost to paint per inch.
So, the total cost is 114242 dollars.
Problem 3
Find the area of a circle whose radius is 239 meters.
The area of the circle = 179,032.89 m²
Explanation
The area of a circle = πr²
Here, r = 239
Therefore, the area of the circle = π × 239² = 3.14 × 239 × 239 = 179,032.89 m².
Problem 4
The area of the square is 57121 cm². Find the perimeter of the square.
The perimeter of the square is
Explanation
The area of the square = a²
Here, the area is 57121 cm²
The length of the side is √57121 = 239
Perimeter of the square = 4a
Here, a = 239
Therefore, the perimeter = 4 × 239 = 956.
Problem 5
Find the square of 240.
The square of 240 is 57600
Explanation
The square of 240 is multiplying 240 by 240.
So, the square = 240 × 240 = 57600
