Problem 1

Find the length of the square, where the area of the square is 13,847,041 cm².

Okay, lets begin

The area of a square = a²

So, the area of a square = 13,847,041 cm²

So, the length = √13,847,041 = 3721.

The length of each side = 3721 cm

Explanation

The length of a square is 3721 cm.

Because the area is 13,847,041 cm² the length is √13,847,041 = 3721.

Problem 2

Sarah wants to install a square-shaped garden with a length of 3721 feet. The cost to install per square foot is 5 dollars. How much will it cost to install the entire garden?

Okay, lets begin

The length of the garden = 3721 feet

The cost to install 1 square foot of garden = 5 dollars.

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

Area of the garden = area of the square = a²

Here a = 3721

Therefore, the area of the garden = 3721² = 13,847,041.

The cost to install the garden = 13,847,041 × 5 = 69,235,205.

The total cost = 69,235,205 dollars

Explanation

To find the cost to install the garden, we multiply the area of the garden by the cost to install per foot.

So, the total cost is 69,235,205 dollars.
