Problem 1

Find the length of the square, where the area of the square is 815,409 cm².

Okay, lets begin

The area of a square = a² So, the area of a square = 815,409 cm² So, the length = √815,409 = 903. The length of each side = 903 cm

Explanation

The length of a square is 903 cm.

Because the area is 815,409 cm² the length is √815,409 = 903.

Problem 2

Anna is building a square garden with a side length of 903 meters. If the cost to fence a meter is 10 dollars, how much will it cost to fence the entire garden?

Okay, lets begin

The length of each side of the garden = 903 meters The cost to fence 1 meter of the garden = 10 dollars. To find the total cost to fence, we find the perimeter of the garden, Perimeter of the garden = 4a Here a = 903 Therefore, the perimeter of the garden = 4 × 903 = 3,612 meters. The cost to fence the garden = 3,612 × 10 = 36,120 dollars. The total cost = 36,120 dollars

Explanation

To find the cost to fence the garden, we multiply the perimeter of the garden by the cost to fence per meter.

So, the total cost is 36,120 dollars.
