Solved Examples on Square of 778
Problem 1
Find the length of the square, where the area of the square is 605,284 cm².
The area of a square = a²
So, the area of a square = 605,284 cm²
So, the length = √605,284 = 778.
The length of each side = 778 cm
Explanation
The length of a square is 778 cm.
Because the area is 605,284 cm², the length is √605,284 = 778.
Problem 2
Emma is planning to tile her square garden of length 778 feet. The cost to tile a foot is 2 dollars. Then how much will it cost to tile the full garden?
The length of the garden = 778 feet
The cost to tile 1 square foot of garden = 2 dollars.
To find the total cost to tile, we find the area of the garden, Area of the garden = area of the square = a²
Here a = 778
Therefore, the area of the garden = 778² = 778 × 778 = 605,284.
The cost to tile the garden = 605,284 × 2 = 1,210,568.
The total cost = 1,210,568 dollars
Explanation
To find the cost to tile the garden, we multiply the area of the garden by the cost to tile per foot.
So, the total cost is 1,210,568 dollars.
Problem 3
Find the area of a circle whose radius is 778 meters.
The area of the circle = 1,901,034.16 m²
Explanation
The area of a circle = πr²
Here, r = 778
Therefore, the area of the circle = π × 778² = 3.14 × 778 × 778 = 1,901,034.16 m².
Problem 4
The area of a square is 605,284 cm². Find the perimeter of the square.
The perimeter of the square is
Explanation
The area of the square = a²
Here, the area is 605,284 cm²
The length of the side is √605,284 = 778
Perimeter of the square = 4a
Here, a = 778
Therefore, the perimeter = 4 × 778 = 3,112.
Problem 5
Find the square of 779.
The square of 779 is 606,841
Explanation
The square of 779 is multiplying 779 by 779.
So, the square = 779 × 779 = 606,841
