For example, the square of 25 is 625, and the square root of 625 is ±25.
Solved Examples on Square of 242
Problem 1
Find the length of the square, where the area of the square is 58,564 cm².
The area of a square = a² So, the area of a square = 58,564 cm² So, the length = √58,564 = 242. The length of each side = 242 cm
Explanation
The length of a square is 242 cm.
Because the area is 58,564 cm² the length is √58,564 = 242.
Problem 2
Anna wants to plant a garden in a square plot of land with a side length of 242 meters. If each meter requires 5 seeds, how many seeds are needed?
The length of the garden = 242 meters Seeds required per square meter = 5 seeds. To find the total seeds needed, we find the area of the garden, Area of the garden = area of the square = a² Here a = 242 Therefore, the area of the garden = 242² = 242 × 242 = 58,564. The seeds needed = 58,564 × 5 = 292,820. The total seeds needed = 292,820
Explanation
To find the total number of seeds needed, we multiply the area of the garden by the seeds required per meter.
So, the total seeds needed are 292,820.
Problem 3
Find the area of a circle whose radius is 242 meters.
The area of the circle = 184,847.36 m²
Explanation
The area of a circle = πr²
Here, r = 242
Therefore, the area of the circle = π × 242² = 3.14 × 242 × 242 = 184,847.36 m².
Problem 4
The area of the square is 58,564 cm². Find the perimeter of the square.
The perimeter of the square is 968 cm.
Explanation
The area of the square = a²
Here, the area is 58,564 cm²
The length of the side is √58,564 = 242
Perimeter of the square = 4a
Here, a = 242
Therefore, the perimeter = 4 × 242 = 968.
Problem 5
Find the square of 243.
The square of 243 is 59,049.
Explanation
The square of 243 is multiplying 243 by 243.
So, the square = 243 × 243 = 59,049.
