Problem 1

A square garden has an area of 427,716 square meters. What is the length of one side of the garden?

Okay, lets begin

The area of a square = a²

So, the area of a square = 427,716 m²

So, the length = √427,716 = 654.

The length of each side = 654 meters

Explanation

The length of a square garden is 654 meters. Because the area is 427,716 m², the length is √427,716 = 654.

Problem 2

Lisa is designing a square-shaped art piece with a side length of 654 cm. If the cost of decorating each square centimeter is 2 dollars, how much will it cost to decorate the entire piece?

Okay, lets begin

The length of the art piece = 654 cm

The cost to decorate 1 square centimeter = 2 dollars.

To find the total cost to decorate, we find the area of the art piece,

Area of the art piece = area of the square = a²

Here a = 654

Therefore, the area of the art piece = 654² = 654 × 654 = 427,716.

The cost to decorate the art piece = 427,716 × 2 = 855,432.

The total cost = 855,432 dollars

Explanation

To find the cost to decorate the art piece, we multiply the area of the piece by the cost to decorate per square centimeter. So, the total cost is 855,432 dollars.
