Problem 1

Find the length of the square, where the area of the square is 589824 cm².

Okay, lets begin

The area of a square = a²

So, the area of a square = 589824 cm²

So, the length = √589824 = 768.

The length of each side = 768 cm

Explanation

The length of a square is 768 cm.

Because the area is 589824 cm², the length is √589824 = 768.

Problem 2

Anna is constructing a square playground of length 768 meters. The cost to lay grass per square meter is 2 dollars. How much will it cost to cover the entire playground with grass?

Okay, lets begin

The length of the playground = 768 meters

The cost to lay grass per square meter = 2 dollars.

To find the total cost to cover the playground, we find the area of the playground,

Area of the playground = area of the square = a²

Here a = 768

Therefore, the area of the playground = 768² = 768 × 768 = 589824.

The cost to cover the playground = 589824 × 2 = 1,179,648.

The total cost = 1,179,648 dollars

Explanation

To find the cost to cover the playground, we multiply the area of the playground by the cost to lay grass per square meter.

So, the total cost is 1,179,648 dollars.

Problem 3

Find the area of a circle whose radius is 768 meters.

Okay, lets begin

The area of the circle = 1,852,208.64 m²

Explanation

The area of a circle = πr²

Here, r = 768

Therefore, the area of the circle = π × 768² = 3.14 × 768 × 768 = 1,852,208.64 m².

Problem 4

The area of the square is 625 cm². Find the perimeter of the square.

Okay, lets begin

The perimeter of the square is 100 cm.

Explanation

The area of the square = a²

Here, the area is 625 cm²

The length of the side is √625 = 25

Perimeter of the square = 4a

Here, a = 25

Therefore, the perimeter = 4 × 25 = 100.
