Problem 1

Find the length of the square, where the area of the square is 35721 cm².

Okay, lets begin

The area of a square = a² So, the area of a square = 35721 cm² So, the length = √35721 = 189. The length of each side = 189 cm

Explanation

The length of a square is 189 cm.

Because the area is 35721 cm² the length is √35721 = 189.

Problem 2

Sarah is planning to tile her square garden of length 189 meters. The cost to tile a meter is 5 dollars. Then how much will it cost to tile the full garden?

Okay, lets begin

The length of the garden = 189 meters

The cost to tile 1 square meter of the garden = 5 dollars.

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

Area of the garden = area of the square = a²

Here a = 189

Therefore, the area of the garden = 189² = 189 × 189 = 35721.

The cost to tile the garden = 35721 × 5 = 178605.

The total cost = 178605 dollars

Explanation

To find the cost to tile the garden, we multiply the area of the garden by the cost to tile per meter.

So, the total cost is 178605 dollars.
