Problem 1

Find the length of a square, where the area of the square is 393129 cm².

Okay, lets begin

The area of a square = a²

So, the area of a square = 393129 cm²

So, the length = √393129 = 627.

The length of each side = 627 cm

Explanation

The length of a square is 627 cm.

Problem 2

Sarah wants to carpet her square room of length 627 feet. The cost to carpet a foot is 10 dollars. How much will it cost to carpet the full room?

Okay, lets begin

The length of the room = 627 feet

The cost to carpet 1 square foot of the room = 10 dollars.

To find the total cost to carpet, find the area of the room,

Area of the room = area of the square = a²

Here a = 627

Therefore, the area of the room = 627² = 627 × 627 = 393129.

The cost to carpet the room = 393129 × 10 = 3931290.

The total cost = 3931290 dollars

Explanation

To find the cost to carpet the room, multiply the area of the room by the cost to carpet per foot. So, the total cost is 3931290 dollars.
