Solved Examples on Square of 545
Problem 1
Find the length of the square, where the area of the square is 297025 cm².
The area of a square = a²
So, the area of a square = 297025 cm²
So, the length = √297025 = 545.
The length of each side = 545 cm
Explanation
The length of a square is 545 cm.
Because the area is 297025 cm², the length is √297025 = 545.
Problem 2
Emily is planning to paint her square wall of length 545 feet. The cost to paint a foot is 5 dollars. Then how much will it cost to paint the full wall?
The length of the wall = 545 feet
The cost to paint 1 square foot of wall = 5 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 = 545
Therefore, the area of the wall = 545² = 545 × 545 = 297025.
The cost to paint the wall = 297025 × 5 = 1485125.
The total cost = 1485125 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 1485125 dollars.
Problem 3
Find the area of a circle whose radius is 545 meters.
The area of the circle = 933450.66 m²
Explanation
The area of a circle = πr²
Here, r = 545
Therefore, the area of the circle = π × 545² = 3.14 × 545 × 545 = 933450.66 m².
Problem 4
The area of the square is 297025 cm². Find the perimeter of the square.
The perimeter of the square is
Explanation
The area of the square = a²
Here, the area is 297025 cm²
The length of the side is √297025 = 545
Perimeter of the square = 4a
Here, a = 545
Therefore, the perimeter = 4 × 545 = 2180.
Problem 5
Find the square of 546.
The square of 546 is 298116
Explanation
The square of 546 is multiplying 546 by 546.
So, the square = 546 × 546 = 298116
