Solved Examples on Square of 438
Problem 1
Find the length of the square, where the area of the square is 191,844 cm².
The area of a square = a²
So, the area of a square = 191,844 cm²
So, the length = √191,844 = 438.
The length of each side = 438 cm
Explanation
The length of a square is 438 cm.
Because the area is 191,844 cm²,
the length is √191,844 = 438.
Problem 2
Susan is planning to paint her square wall of length 438 feet. The cost to paint a foot is 3 dollars. Then how much will it cost to paint the full wall?
The length of the wall = 438 feet
The cost to paint 1 square foot of wall = 3 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 = 438
Therefore, the area of the wall = 438² = 438 × 438 = 191,844.
The cost to paint the wall = 191,844 × 3 = 575,532.
The total cost = 575,532 dollars
Explanation
To find the cost to paint the wall, we multiply the area of the wall by the cost to paint per foot. So, the total cost is 575,532 dollars.
Problem 3
Find the area of a circle whose radius is 438 meters.
The area of the circle = 603,185.76 m²
Explanation
The area of a circle = πr²
Here, r = 438
Therefore, the area of the circle = π × 438² = 3.14 × 438 × 438 = 603,185.76 m².
Problem 4
The area of the square is 1936 cm². Find the perimeter of the square.
The perimeter of the square is
Explanation
The area of the square = a²
Here, the area is 1936 cm²
The length of the side is √1936 = 44
Perimeter of the square = 4a
Here, a = 44
Therefore, the perimeter = 4 × 44 = 176.
Problem 5
Find the square of 439.
The square of 439 is 192,721
Explanation
The square of 439 is multiplying 439 by 439.
So, the square = 439 × 439 = 192,721
