Problem 1

Find the length of the square, where the area of the square is 90000 cm².

Okay, lets begin

The area of a square = a²

So, the area of a square = 90000 cm²

So, the length = √90000 = 300.

The length of each side = 300 cm

Explanation

The length of a square is 300 cm.

Because the area is 90000 cm² the length is √90000 = 300.

Problem 2

Sara is planning to paint her square wall of length 300 feet. The cost to paint a foot is 2 dollars. Then how much will it cost to paint the full wall?

Okay, lets begin

The length of the wall = 300 feet

The cost to paint 1 square foot of wall = is 2 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 = 300

Therefore, the area of the wall = 300² = 300 × 300 = 90000.

The cost to paint the wall = 90000 × 2 = 180000.

The total cost = 180000 dollars

Explanation

To find the cost to paint the wall, we multiply the area of the wall by the cost to paint per foot. So, the total cost is 180000 dollars.

Problem 3

Find the area of a circle whose radius is 300 meters.

Okay, lets begin

The area of the circle = 282743.3 m²

Explanation

The area of a circle = πr²

Here, r = 300

Therefore, the area of the circle = π × 300² = 3.14 × 300 × 300 = 282743.3 m².

Problem 4

The area of the square is 90000 cm². Find the perimeter of the square.

Okay, lets begin

The perimeter of the square is 1200 cm.

Explanation

The area of the square = a²

Here, the area is 90000 cm²

The length of the side is √90000 = 300

Perimeter of the square = 4a

Here, a = 300

Therefore, the perimeter = 4 × 300 = 1200.
