Problem 1

Find the length of a square, where the area of the square is 193,600 cm².

Okay, lets begin

The area of a square = a²

So, the area of a square = 193,600 cm²

So, the length = √193,600 = 440.

The length of each side = 440 cm

Explanation

The length of a square is 440 cm. Because the area is 193,600 cm², the length is √193,600 = 440.

Problem 2

Tom is planning to paint his square wall of length 440 feet. The cost to paint a foot is 3 dollars. Then how much will it cost to paint the full wall?

Okay, lets begin

The length of the wall = 440 feet

The cost to paint 1 square foot of wall = 3 dollars.

To find the total cost to paint, we find the area of the wall,

Area of the wall = area of the square = a²

Here a = 440

Therefore, the area of the wall = 440² = 440 × 440 = 193,600.

The cost to paint the wall = 193,600 × 3 = 580,800.

The total cost = 580,800 dollars

Explanation

To find the cost to paint the wall, we multiply the area of the wall by the cost to paint per square foot. So, the total cost is 580,800 dollars.

Problem 3

Find the area of a circle whose radius is 440 meters.

Okay, lets begin

The area of the circle = 608,201.6 m²

Explanation

The area of a circle = πr²

Here, r = 440

Therefore, the area of the circle = π × 440² = 3.14 × 440 × 440 = 608,201.6 m².
