Problem 1

Find the length of a square, where the area of the square is 243,049 cm².

Okay, lets begin

The area of a square = a²

So, the area of a square = 243,049 cm²

So, the length = √243,049 = 493.

The length of each side = 493 cm

Explanation

The length of a square is 493 cm.

Because the area is 243,049 cm² the length is √243,049 = 493.

Problem 2

Sarah is planning to tile her square garden of length 493 feet. The cost to tile a foot is 5 dollars. Then how much will it cost to tile the full garden?

Okay, lets begin

The length of the garden = 493 feet

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

To find the total cost to tile, we find the area of the garden.

Area of the garden = area of the square = a²

Here a = 493

Therefore, the area of the garden = 493² = 493 × 493 = 243,049.

The cost to tile the garden = 243,049 × 5 = 1,215,245.

The total cost = 1,215,245 dollars

Explanation

To find the cost to tile the garden, we multiply the area of the garden by the cost to tile per foot. So, the total cost is 1,215,245 dollars.
