Solved Examples on Square of 189
Problem 1
Find the length of the square, where the area of the square is 35721 cm².
The area of a square = a² So, the area of a square = 35721 cm² So, the length = √35721 = 189. The length of each side = 189 cm
Explanation
The length of a square is 189 cm.
Because the area is 35721 cm² the length is √35721 = 189.
Problem 2
Sarah is planning to tile her square garden of length 189 meters. The cost to tile a meter is 5 dollars. Then how much will it cost to tile the full garden?
The length of the garden = 189 meters
The cost to tile 1 square meter of the garden = 5 dollars.
To find the total cost to tile, we find the area of the garden,
Area of the garden = area of the square = a²
Here a = 189
Therefore, the area of the garden = 189² = 189 × 189 = 35721.
The cost to tile the garden = 35721 × 5 = 178605.
The total cost = 178605 dollars
Explanation
To find the cost to tile the garden, we multiply the area of the garden by the cost to tile per meter.
So, the total cost is 178605 dollars.
Problem 3
Find the area of a circle whose radius is 189 meters.
The area of the circle = 112,711.86 m²
Explanation
The area of a circle = πr² Here, r = 189
Therefore, the area of the circle = π × 189² = 3.14 × 189 × 189 = 112,711.86 m².
Problem 4
The area of the square is 35721 cm². Find the perimeter of the square.
The perimeter of the square is 756 cm
Explanation
The area of the square = a²
Here, the area is 35721 cm²
The length of the side is √35721 = 189
Perimeter of the square = 4a Here, a = 189
Therefore, the perimeter = 4 × 189 = 756.
Problem 5
Find the square of 190.
The square of 190 is 36100
Explanation
The square of 190 is multiplying 190 by 190.
So, the square = 190 × 190 = 36100
