Solved Examples on Square of 198
Problem 1
A plot of land has an area of 39,204 m². What is the length of each side of the plot if it is square-shaped?
The area of a square = a² So, the area of a square = 39,204 m² So, the length = √39,204 = 198. The length of each side = 198 m
Explanation
The length of the square plot is 198 meters.
Because the area is 39,204 m², the length is √39,204 = 198.
Problem 2
A square garden has a length of 198 feet. If the cost to plant flowers is $2 per square foot, how much will it cost to plant the entire garden?
The length of the garden = 198 feet The cost to plant 1 square foot of garden = $2. To find the total cost to plant, we find the area of the garden, Area of the garden = area of the square = a² Here a = 198 Therefore, the area of the garden = 198² = 198 × 198 = 39,204. The cost to plant the garden = 39,204 × $2 = $78,408. The total cost = $78,408
Explanation
To find the cost to plant the garden, we multiply the area of the garden by the cost to plant per foot.
So, the total cost is $78,408.
Problem 3
Find the area of a circle whose radius is 198 meters.
The area of the circle = 123,566.64 m²
Explanation
The area of a circle = πr²
Here, r = 198
Therefore, the area of the circle = π × 198² = 3.14 × 198 × 198 = 123,566.64 m².
Problem 4
The area of a square is 39,204 cm². Find the perimeter of the square.
The perimeter of the square is
Explanation
The area of the square = a²
Here, the area is 39,204 cm²
The length of the side is √39,204 = 198
Perimeter of the square = 4a
Here, a = 198
Therefore, the perimeter = 4 × 198 = 792.
Problem 5
Find the square of 199.
The square of 199 is 39,601
Explanation
The square of 199 is multiplying 199 by 199.
So, the square = 199 × 199 = 39,601
