Solved Examples on Square of 542
Problem 1
Find the length of the square, where the area of the square is 293,764 cm².
The area of a square = a²
So, the area of a square = 293,764 cm²
So, the length = √293,764 = 542.
The length of each side = 542 cm
Explanation
The length of a square is 542 cm.
Because the area is 293,764 cm² the length is √293,764 = 542.
Problem 2
Lisa wants to carpet her square room with a side length of 542 inches. The cost to carpet a square inch is 2 dollars. How much will it cost to carpet the full room?
The length of the room = 542 inches
The cost to carpet 1 square inch of the room = 2 dollars.
To find the total cost to carpet, we find the area of the room,
Area of the room = area of the square = a²
Here a = 542
Therefore, the area of the room = 542² = 542 × 542 = 293,764.
The cost to carpet the room = 293,764 × 2 = 587,528.
The total cost = 587,528 dollars
Explanation
To find the cost to carpet the room, we multiply the area of the room by the cost to carpet per square inch.
So, the total cost is 587,528 dollars.
Problem 3
Find the area of a circle whose radius is 542 meters.
The area of the circle = 923,628.32 m²
Explanation
The area of a circle = πr² Here, r = 542 Therefore, the area of the circle = π × 542² = 3.14 × 542 × 542 = 923,628.32 m².
Problem 4
The area of the square is 293,764 cm². Find the perimeter of the square.
The perimeter of the square is 2,168 cm.
Explanation
The area of the square = a² Here, the area is 293,764 cm² The length of the side is √293,764 = 542 Perimeter of the square = 4a Here, a = 542 Therefore, the perimeter = 4 × 542 = 2,168.
Problem 5
Find the square of 543.
The square of 543 is 294,849
Explanation
The square of 543 is multiplying 543 by 543. So, the square = 543 × 543 = 294,849
