Problem 1

Find the length of the square, where the area of the square is 970225 cm².

Okay, lets begin

The area of a square = a²

So, the area of a square = 970225 cm²

So, the length = √970225 = 985.

The length of each side = 985 cm

Explanation

The length of a square is 985 cm. Because the area is 970225 cm² the length is √970225 = 985.

Problem 2

Sarah wants to cover her square garden with grass. The garden has a side length of 985 meters. The cost to cover one square meter with grass is 2 dollars. What will be the total cost to cover the garden?

Okay, lets begin

The length of the garden = 985 meters

The cost to cover 1 square meter of the garden = 2 dollars.

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

Area of the garden = area of the square = a²

Here a = 985

Therefore, the area of the garden = 985² = 985 × 985 = 970225.

The cost to cover the garden = 970225 × 2 = 1940450.

The total cost = 1940450 dollars

Explanation

To find the cost to cover the garden, we multiply the area of the garden by the cost to cover per square meter. So, the total cost is 1940450 dollars.

Problem 3

Find the area of a circle whose radius is 985 meters.

Okay, lets begin

The area of the circle = 3,048,930.25 m²

Explanation

The area of a circle = πr²

Here, r = 985

Therefore, the area of the circle = π × 985²

= 3.14 × 985 × 985

= 3,048,930.25 m².
