Problem 1

Find the length of the square, where the area of the square is 404,496 cm².

Okay, lets begin

The area of a square = a²

So, the area of a square = 404,496 cm²

So, the length = √404,496 = 636.

The length of each side = 636 cm

Explanation

The length of a square is 636 cm.

Because the area is 404,496 cm², the length is √404,496 = 636.

Problem 2

Emma wants to tile her square floor with tiles of length 636 feet. If each tile costs 5 dollars, how much will it cost to tile the entire floor?

Okay, lets begin

The length of the floor = 636 feet

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

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

Area of the floor = area of the square = a²

Here a = 636

Therefore, the area of the floor = 636² = 636 × 636 = 404,496.

The cost to tile the floor = 404,496 × 5 = 2,022,480.

The total cost = 2,022,480 dollars

Explanation

To find the cost to tile the floor, we multiply the area of the floor by the cost to tile per foot. So, the total cost is 2,022,480 dollars.
