Solved Examples on Square of 947
Problem 1
Find the area of a square plot with side length 947 meters.
The area of the square = side²
So, the area = 947² = 947 × 947 = 896,809 m².
Explanation
The area of a square plot is calculated by multiplying the side length by itself. Here, the side length is 947 meters, so the area is 896,809 m².
Problem 2
A company wants to install a square-shaped solar panel with sides of 947 centimeters. If the cost to install each square centimeter is $2, what will be the total cost?
The side length of the solar panel = 947 cm
The cost to install 1 square centimeter = $2
To find the total cost to install, we find the area of the panel, Area = side²
Here, side = 947
Therefore, the area = 947² = 947 × 947 = 896,809 cm².
The cost to install the panel = 896,809 × 2 = 1,793,618.
The total cost = $1,793,618
Explanation
To find the cost to install the solar panel, we multiply the area of the panel by the cost per square centimeter. So, the total cost is $1,793,618.
Problem 3
Find the area of a circle with a radius of 947 meters.
The area of the circle = 2,817,530.22 m²
Explanation
The area of a circle = πr²
Here, r = 947
Therefore, the area of the circle = π × 947² = 3.14 × 947 × 947 = 2,817,530.22 m².
Problem 4
The area of a square is 896,809 cm². Find the perimeter of the square.
The perimeter of the square is 3,788 cm
Explanation
The area of the square = side²
Here, the area is 896,809 cm²
The length of the side is √896,809 = 947
Perimeter of the square = 4 × side
Here, side = 947
Therefore, the perimeter = 4 × 947 = 3,788 cm.
Problem 5
Find the square of 950.
The square of 950 is 902,500
Explanation
The square of 950 is multiplying 950 by 950.
So, the square = 950 × 950 = 902,500
