Problem 1

Find the side length of a square, where the area of the square is 242,064 cm².

Okay, lets begin

The area of a square = a²

So, the area of a square = 242,064 cm²

So, the length = √242,064 = 492.

The length of each side = 492 cm

Explanation

The length of a square is 492 cm.

Because the area is 242,064 cm², the length is √242,064 = 492.

Problem 2

Emily is planning to paint her square garden wall of length 492 feet. The cost to paint a square foot is 5 dollars. How much will it cost to paint the full wall?

Okay, lets begin

The length of the wall = 492 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 = 492

Therefore, the area of the wall = 492² = 492 × 492 = 242,064.

The cost to paint the wall = 242,064 × 5 = 1,210,320.

The total cost = 1,210,320 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 1,210,320 dollars.

Problem 3

Find the area of a circle whose radius is 492 meters.

Okay, lets begin

The area of the circle = 760,864.56 m²

Explanation

The area of a circle = πr²

Here, r = 492

Therefore, the area of the circle = π × 492² = 3.14 × 492 × 492 = 760,864.56 m².

Problem 4

The area of a square is 242,064 cm². Find the perimeter of the square.

Okay, lets begin

The perimeter of the square is 1,968 cm.

Explanation

The area of the square = a²

Here, the area is 242,064 cm²

The length of the side is √242,064 = 492

Perimeter of the square = 4a

Here, a = 492

Therefore, the perimeter = 4 × 492 = 1,968 cm.
