Problem 1

Find the length of the square, where the area of the square is 461041 cm².

Okay, lets begin

The area of a square = a²

So, the area of a square = 461041 cm²

So, the length = √461041 = 679.

The length of each side = 679 cm

Explanation

The length of a square is 679 cm. Because the area is 461041 cm², the length is √461041 = 679.

Problem 2

Sara is planning to carpet her square hall of length 679 feet. The cost to carpet a foot is 5 dollars. Then how much will it cost to carpet the full hall?

Okay, lets begin

The length of the hall = 679 feet

The cost to carpet 1 square foot of hall = 5 dollars.

To find the total cost to carpet, we find the area of the hall,

Area of the hall = area of the square = a²

Here a = 679

Therefore, the area of the hall = 679² = 679 × 679 = 461041.

The cost to carpet the hall = 461041 × 5 = 2305205.

The total cost = 2305205 dollars

Explanation

To find the cost to carpet the hall, we multiply the area of the hall by the cost to carpet per foot.

So, the total cost is 2305205 dollars.

Find the area of a circle whose radius is 679 meters.

Okay, lets begin

The area of the circle = 1,448,428.66 m²

Explanation

The area of a circle = πr²

Here, r = 679

Therefore, the area of the circle = π × 679²

= 3.14 × 679 × 679

= 1,448,428.66 m².
