Solved Examples on Square of 7200
Problem 1
Find the length of the square, where the area of the square is 51,840,000 cm².
The area of a square = a² So, the area of a square = 51,840,000 cm² So, the length = √51,840,000 = 7200. The length of each side = 7200 cm
Explanation
The length of a square is 7200 cm.
Because the area is 51,840,000 cm² the length is √51,840,000 = 7200.
Problem 2
Mia is planning to carpet her square room of length 7200 feet. The cost to carpet a foot is 5 dollars. Then how much will it cost to carpet the full room?
The length of the room = 7200 feet The cost to carpet 1 square foot of room = 5 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 = 7200 Therefore, the area of the room = 7200² = 7200 × 7200 = 51,840,000. The cost to carpet the room = 51,840,000 × 5 = 259,200,000. The total cost = 259,200,000 dollars
Explanation
To find the cost to carpet the room, we multiply the area of the room by the cost to carpet per foot.
So, the total cost is 259,200,000 dollars.
Problem 3
Find the area of a circle whose radius is 7200 meters.
The area of the circle = 162,854,400 m²
Explanation
The area of a circle = πr²
Here, r = 7200
Therefore, the area of the circle = π × 7200² = 3.14 × 7200 × 7200 = 162,854,400 m².
Problem 4
The area of the square is 51,840,000 cm². Find the perimeter of the square.
The perimeter of the square is 28,800 cm.
Explanation
The area of the square = a²
Here, the area is 51,840,000 cm²
The length of the side is √51,840,000 = 7200
Perimeter of the square = 4a
Here, a = 7200
Therefore, the perimeter = 4 × 7200 = 28,800.
Problem 5
Find the square of 7300.
The square of 7300 is 53,290,000.
Explanation
The square of 7300 is multiplying 7300 by 7300.
So, the square = 7300 × 7300 = 53,290,000.
