Solved Examples on Square of 1091
Problem 1
Find the length of the square, where the area of the square is 1,190,281 cm².
The area of a square = a²
So, the area of a square = 1,190,281 cm²
So, the length = √1,190,281 = 1091.
The length of each side = 1091 cm
Explanation
The length of a square is 1091 cm.
Because the area is 1,190,281 cm², the length is √1,190,281 = 1091.
Problem 2
Sarah is planning to carpet her square room of length 1091 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 = 1091 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 = 1091
Therefore, the area of the room = 1091² = 1091 × 1091 = 1,190,281.
The cost to carpet the room = 1,190,281 × 5 = 5,951,405.
The total cost = 5,951,405 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 5,951,405 dollars.
Problem 3
Find the area of a circle whose radius is 1091 meters.
The area of the circle = 3,740,041.98 m²
Explanation
The area of a circle = πr²
Here, r = 1091
Therefore, the area of the circle = π × 1091² = 3.14 × 1091 × 1091 = 3,740,041.98 m².
Problem 4
The area of the square is 1,190,281 cm². Find the perimeter of the square.
The perimeter of the square is 4364 cm.
Explanation
The area of the square = a²
Here, the area is 1,190,281 cm²
The length of the side is √1,190,281 = 1091
Perimeter of the square = 4a
Here, a = 1091
Therefore, the perimeter = 4 × 1091 = 4364.
Problem 5
Find the square of 1092.
The square of 1092 is 1,192,464.
Explanation
The square of 1092 is multiplying 1092 by 1092.
So, the square = 1092 × 1092 = 1,192,464.
