Problem 1

Find the length of the square, where the area of the square is 1,040,400 cm².

Okay, lets begin

The area of a square = a²

So, the area of a square = 1,040,400 cm²

So, the length = √1,040,400 = 1020.

The length of each side = 1020 cm

Explanation

The length of a square is 1020 cm.

Because the area is 1,040,400 cm² the length is √1,040,400 = 1020.

Problem 2

Alice is planning to paint her square wall of length 1020 feet. The cost to paint a foot is 5 dollars. Then how much will it cost to paint the full wall?

Okay, lets begin

The length of the wall = 1020 feet

The cost to paint 1 square foot of wall = 5 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 = 1020

Therefore, the area of the wall = 1020² = 1020 × 1020 = 1,040,400.

The cost to paint the wall = 1,040,400 × 5 = 5,202,000.

The total cost = 5,202,000 dollars

Explanation

To find the cost to paint the wall, we multiply the area of the wall by cost to paint per foot. So, the total cost is 5,202,000 dollars.

Problem 3

Find the area of a circle whose radius is 1020 meters.

Okay, lets begin

The area of the circle = 3,271,464 m²

Explanation

The area of a circle = πr²

Here, r = 1020

Therefore, the area of the circle = π × 1020² = 3.14 × 1020 × 1020 = 3,271,464 m².

Problem 4

The area of the square is 1,040,400 cm². Find the perimeter of the square.

Okay, lets begin

The perimeter of the square is 4080 cm.

Explanation

The area of the square = a²

Here, the area is 1,040,400 cm²

The length of the side is √1,040,400 = 1020

Perimeter of the square = 4a

Here, a = 1020

Therefore, the perimeter = 4 × 1020 = 4080.

Problem 5

Find the square of 1021.

Okay, lets begin

The square of 1021 is 1,042,441.

Explanation

The square of 1021 is multiplying 1021 by 1021.

So, the square = 1021 × 1021 = 1,042,441
