Solved Examples on Square of 654
Problem 1
A square garden has an area of 427,716 square meters. What is the length of one side of the garden?
The area of a square = a²
So, the area of a square = 427,716 m²
So, the length = √427,716 = 654.
The length of each side = 654 meters
Explanation
The length of a square garden is 654 meters. Because the area is 427,716 m², the length is √427,716 = 654.
Problem 2
Lisa is designing a square-shaped art piece with a side length of 654 cm. If the cost of decorating each square centimeter is 2 dollars, how much will it cost to decorate the entire piece?
The length of the art piece = 654 cm
The cost to decorate 1 square centimeter = 2 dollars.
To find the total cost to decorate, we find the area of the art piece,
Area of the art piece = area of the square = a²
Here a = 654
Therefore, the area of the art piece = 654² = 654 × 654 = 427,716.
The cost to decorate the art piece = 427,716 × 2 = 855,432.
The total cost = 855,432 dollars
Explanation
To find the cost to decorate the art piece, we multiply the area of the piece by the cost to decorate per square centimeter. So, the total cost is 855,432 dollars.
Problem 3
Find the area of a square park whose side is 654 meters.
The area of the square park = 427,716 m²
Explanation
The area of a square = a²
Here, a = 654
Therefore, the area of the park = 654² = 654 × 654 = 427,716 m².
Problem 4
The area of a square is 427,716 m². Find the perimeter of the square.
The perimeter of the square is 2,616 meters.
Explanation
The area of the square = a²
Here, the area is 427,716 m²
The length of the side is √427,716 = 654
Perimeter of the square = 4a
Here, a = 654
Therefore, the perimeter = 4 × 654 = 2,616 meters.
Problem 5
Find the square of 655.
The square of 655 is 429,025.
Explanation
The square of 655 is multiplying 655 by 655.
So, the square = 655 × 655 = 429,025
