Problem 1

Find the side length of the square, where the area of the square is 405,769 cm².

Okay, lets begin

The area of a square = a²

So, the area of a square = 405,769 cm²

So, the side length = √405,769 = 637.

The side length of each side = 637 cm

Explanation

The side length of a square is 637 cm.

Because the area is 405,769 cm², the side length is √405,769 = 637.

Problem 2

Anna wants to lay tiles on her square patio of side length 637 feet. The cost to lay a square foot of tiles is 5 dollars. How much will it cost to tile the full patio?

Okay, lets begin

The side length of the patio = 637 feet

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

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

Area of the patio = area of the square = a²

Here a = 637

Therefore, the area of the patio = 637² = 637 × 637 = 405,769.

The cost to tile the patio = 405,769 × 5 = 2,028,845.

The total cost = 2,028,845 dollars

Explanation

To find the cost to tile the patio, we multiply the area of the patio by the cost to tile per square foot. So, the total cost is 2,028,845 dollars.
