Solved Examples on Square of 779
Problem 1
Find the length of the square, where the area of the square is 606,841 cm².
The area of a square = a²
So, the area of a square = 606,841 cm²
So, the length = √606,841 = 779.
The length of each side = 779 cm
Explanation
The length of a square is 779 cm.
Because the area is 606,841 cm², the length is √606,841 = 779.
Problem 2
Anna is planning to carpet her square room of length 779 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 = 779 feet
The cost to carpet 1 square foot of the 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 = 779
Therefore, the area of the room = 779² = 779 × 779 = 606,841.
The cost to carpet the room = 606,841 × 5 = 3,034,205.
The total cost = 3,034,205 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 3,034,205 dollars.
Problem 3
Find the area of a circle whose radius is 779 meters.
The area of the circle = 1,908,401.96 m²
Explanation
The area of a circle = πr²
Here, r = 779
Therefore, the area of the circle = π × 779² = 3.14 × 779 × 779 = 1,908,401.96 m².
Problem 4
The area of the square is 608,641 cm². Find the perimeter of the square.
The perimeter of the square is
Explanation
The area of the square = a²
Here, the area is 608,641 cm²
The length of the side is √608,641 = 779
Perimeter of the square = 4a
Here, a = 779
Therefore, the perimeter = 4 × 779 = 3,116.
Problem 5
Find the square of 780.
The square of 780 is 608,400
Explanation
The square of 780 is multiplying 780 by 780.
So, the square = 780 × 780 = 608,400
