Solved Examples on Square of 11111111
Problem 1
Find the length of the square, where the area of the square is 123456787654321 cm².
The area of a square = a² So, the area of a square = 123456787654321 cm² So, the length = √123456787654321 = 11111111. The length of each side = 11111111 cm
Explanation
The length of a square is 11111111 cm.
Because the area is 123456787654321 cm², the length is √123456787654321 = 11111111.
Problem 2
Sarah wants to cover her square garden of length 11111111 feet with tiles. If each tile costs 2 dollars, how much will it cost to cover the full garden?
The length of the garden = 11111111 feet The cost to cover 1 square foot of garden = 2 dollars. To find the total cost to cover, we find the area of the garden, Area of the garden = area of the square = a² Here a = 11111111 Therefore, the area of the garden = 11111111² = 123456787654321. The cost to cover the garden = 123456787654321 × 2 = 246913575308642. The total cost = 246913575308642 dollars
Explanation
To find the cost to cover the garden, we multiply the area of the garden by the cost to cover per foot.
So, the total cost is 246913575308642 dollars.
Problem 3
Find the area of a circle whose radius is 11111111 meters.
The area of the circle = 387850640124.5 m²
Explanation
The area of a circle = πr²
Here, r = 11111111
Therefore, the area of the circle = π × 11111111² = 3.14 × 11111111 × 11111111 = 387850640124.5 m².
Problem 4
The area of a square is 123456787654321 cm². Find the perimeter of the square.
The perimeter of the square is 44444444 cm.
Explanation
The area of the square = a²
Here, the area is 123456787654321 cm²
The length of the side is √123456787654321 = 11111111
Perimeter of the square = 4a
Here, a = 11111111
Therefore, the perimeter = 4 × 11111111 = 44444444.
Problem 5
Find the square of 12345.
The square of 12345 is 152399025.
Explanation
The square of 12345 is multiplying 12345 by 12345.
So, the square = 12345 × 12345 = 152399025.
