Solved Examples on Square of 945
Problem 1
Find the length of the square, where the area of the square is 893025 cm².
The area of a square = a²
So, the area of a square = 893025 cm²
So, the length = √893025 = 945.
The length of each side = 945 cm
Explanation
The length of a square is 945 cm.
Because the area is 893025 cm², the length is √893025 = 945.
Problem 2
Anna is planning to carpet her square living room of length 945 feet. The cost to carpet a foot is 5 dollars. Then how much will it cost to carpet the full room?
The length of the room = 945 feet
The cost to carpet 1 square foot of room = 5 dollars.
To find the total cost to carpet, we find the area of the room,
Area of the room = area of the square = a²
Here a = 945
Therefore, the area of the room = 945² = 945 × 945 = 893025.
The cost to carpet the room = 893025 × 5 = 4465125.
The total cost = 4465125 dollars
Explanation
To find the cost to carpet the room,
we multiply the area of the room by the cost to carpet per foot. So, the total cost is 4465125 dollars.
Problem 3
Find the area of a circle whose radius is 945 meters.
The area of the circle = 2804978.25 m²
Explanation
The area of a circle = πr²
Here, r = 945
Therefore, the area of the circle = π × 945² = 3.14 × 945 × 945 = 2804978.25 m².
Problem 4
The area of the square is 893025 cm². Find the perimeter of the square.
The perimeter of the square is 3780 cm.
Explanation
The area of the square = a²
Here, the area is 893025 cm²
The length of the side is √893025 = 945
Perimeter of the square = 4a
Here, a = 945
Therefore, the perimeter = 4 × 945 = 3780.
Problem 5
Find the square of 946.
The square of 946 is 895716.
Explanation
The square of 946 is multiplying 946 by 946. So, the square = 946 × 946 = 895716.
