Problem 1

Find the length of the square, where the area of the square is 0 cm².

Okay, lets begin

The area of a square = a²

So, the area of a square = 0 cm²

So, the length = √0 = 0.

The length of each side = 0 cm

Explanation

The length of a square is 0 cm.

Because the area is 0 cm², the length is √0 = 0.

Problem 2

A painter has no wall to paint. How much will it cost to paint the wall if the cost to paint a foot is 3 dollars?

Okay, lets begin

Since there is no wall, the cost to paint the wall is 0 dollars.

Explanation

To find the cost to paint the wall, we multiply the area of the wall by the cost to paint per foot. Since there is no wall, the cost is 0 dollars.

Problem 3

Find the area of a circle whose radius is 0 meters.

Okay, lets begin

The area of the circle = 0 m²

Explanation

The area of a circle = πr²

Here, r = 0

Therefore, the area of the circle = π × 0² = 3.14 × 0 × 0 = 0 m².

Problem 4

The area of the square is 0 cm². Find the perimeter of the square.

Okay, lets begin

The perimeter of the square is 0.

Explanation

The area of the square = a²

Here, the area is 0 cm²

The length of the side is √0 = 0

Perimeter of the square = 4a

Here, a = 0

Therefore, the perimeter = 4 × 0 = 0.
