Problem 1

Find the length of the square, where the area of the square is 184,900 cm².

Okay, lets begin

The area of a square = a²

So, the area of a square = 184,900 cm²

So, the length = √184,900 = 430.

The length of each side = 430 cm

Explanation

The length of a square is 430 cm.

Because the area is 184,900 cm² the length is √184,900 = 430.

Problem 2

Anna wants to put a new carpet on her square room floor of length 430 feet. The cost to carpet a square foot is 5 dollars. Then how much will it cost to carpet the full floor?

Okay, lets begin

The length of the room = 430 feet

The cost to carpet 1 square foot of floor = 5 dollars.

To find the total cost to carpet, we find the area of the floor,

Area of the floor = area of the square = a²

Here a = 430

Therefore, the area of the floor = 430² = 430 × 430 = 184,900.

The cost to carpet the floor = 184,900 × 5 = 924,500.

The total cost = 924,500 dollars

Explanation

To find the cost to carpet the floor, we multiply the area of the floor by cost to carpet per foot. So, the total cost is 924,500 dollars.

Explanation

The area of the square = a²

Here, the area is 184,900 cm²

The length of the side is √184,900 = 430

Perimeter of the square = 4a

Here, a = 430

Therefore, the perimeter = 4 × 430 = 1,720 cm.
