Problem 1

Find the length of the square, where the area of the square is 620,944 cm².

Okay, lets begin

The area of a square = a²

So, the area of a square = 620,944 cm²

So, the length = √620,944 = 788.

The length of each side = 788 cm

Explanation

The length of a square is 788 cm.

Because the area is 620,944 cm² the length is √620,944 = 788.

Problem 2

Lisa is planning to carpet her square room of length 788 feet. The cost to carpet a foot is 10 dollars. Then how much will it cost to carpet the full room?

Okay, lets begin

The length of the room = 788 feet

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

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

Area of the room = area of the square = a²

Here a = 788

Therefore, the area of the room = 788² = 788 × 788 = 620,944.

The cost to carpet the room = 620,944 × 10 = 6,209,440.

The total cost = 6,209,440 dollars

Explanation

To find the cost to carpet the room, we multiply the area of the room by cost to carpet per foot.

So, the total cost is 6,209,440 dollars.
