Solved Examples on Square of 777
Problem 1
Find the length of the square, where the area of the square is 603729 cm².
The area of a square = a²
So, the area of a square = 603729 cm²
So, the length = √603729 = 777.
The length of each side = 777 cm
Explanation
The length of a square is 777 cm.
Because the area is 603729 cm², the length is √603729 = 777.
Problem 2
Alex is planning to tile his square floor of length 777 feet. The cost to tile a foot is 5 dollars. Then how much will it cost to tile the full floor?
The length of the floor = 777 feet
The cost to tile 1 square foot of floor = 5 dollars.
To find the total cost to tile, we find the area of the floor, Area of the floor = area of the square = a²
Here a = 777
Therefore, the area of the floor = 777² = 777 × 777 = 603729.
The cost to tile the floor = 603729 × 5 = 3018645.
The total cost = 3018645 dollars
Explanation
To find the cost to tile the floor, we multiply the area of the floor by the cost to tile per foot.
So, the total cost is 3018645 dollars.
Problem 3
Find the area of a circle whose radius is 777 meters.
The area of the circle = 1,896,406.77 m²
Explanation
The area of a circle = πr²
Here, r = 777
Therefore, the area of the circle = π × 777² = 3.14 × 777 × 777 = 1,896,406.77 m².
Problem 4
The area of the square is 603,729 cm². Find the perimeter of the square.
The perimeter of the square is
Explanation
The area of the square = a²
Here, the area is 603,729 cm²
The length of the side is √603,729 = 777
Perimeter of the square = 4a
Here, a = 777
Therefore, the perimeter = 4 × 777 = 3108.
Problem 5
Find the square of 778.
The square of 778 is 605,284
Explanation
The square of 778 is multiplying 778 by 778.
So, the square = 778 × 778 = 605,284
