For example, the square of 25 is 625, and the square root of 625 is ±25.
Solved Examples on Square of 385
Problem 1
Find the length of the square, where the area of the square is 148225 cm².
The area of a square = a² So, the area of a square = 148225 cm² So, the length = √148225 = 385. The length of each side = 385 cm
Explanation
The length of a square is 385 cm.
Because the area is 148225 cm², the length is √148225 = 385.
Problem 2
Emily is planning to paint her square wall of length 385 feet. The cost to paint a foot is 2 dollars. Then how much will it cost to paint the full wall?
The length of the wall = 385 feet The cost to paint 1 square foot of wall = 2 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 = 385 Therefore, the area of the wall = 385² = 385 × 385 = 148225. The cost to paint the wall = 148225 × 2 = 296450. The total cost = 296450 dollars
Explanation
To find the cost to paint the wall, we multiply the area of the wall by cost to paint per foot.
So, the total cost is 296450 dollars.
Problem 3
Find the area of a circle whose radius is 385 meters.
The area of the circle = 465,181.82 m²
Explanation
The area of a circle = πr²
Here, r = 385
Therefore, the area of the circle = π × 385² = 3.14 × 385 × 385 = 465181.82 m².
Problem 4
The area of the square is 148225 cm². Find the perimeter of the square.
The perimeter of the square is 1540 cm.
Explanation
The area of the square = a²
Here, the area is 148225 cm²
The length of the side is √148225 = 385
Perimeter of the square = 4a
Here, a = 385
Therefore, the perimeter = 4 × 385 = 1540.
Problem 5
Find the square of 386.
The square of 386 is 148996.
Explanation
The square of 386 is multiplying 386 by 386.
So, the square = 386 × 386 = 148996.
