Problem 1

A homeowner wants to tile a square floor with an area of 39601 square feet. What is the length of one side of the floor?

Okay, lets begin

The area of a square = a² So, the area of a square = 39601 square feet So, the length = √39601 = 199. The length of each side = 199 feet

Explanation

The length of a square floor is 199 feet.

Because the area is 39601 square feet the length is √39601 = 199.

Problem 2

A company is building a square garden with each side measuring 199 meters. The maintenance cost is 2 dollars per square meter. What will be the total maintenance cost for the garden?

Okay, lets begin

The length of the garden = 199 meters The cost to maintain 1 square meter of the garden = 2 dollars. To find the total cost to maintain, we find the area of the garden, Area of the garden = area of the square = a² Here a = 199 Therefore, the area of the garden = 199² = 199 × 199 = 39601. The cost to maintain the garden = 39601 × 2 = 79202. The total cost = 79202 dollars

Explanation

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

So, the total cost is 79202 dollars.
