Problem 1

Find the length of the square, where the area of the square is 244,036 cm².

Okay, lets begin

The area of a square = a²

So, the area of a square = 244,036 cm²

So, the length = √244,036 = 494.

The length of each side = 494 cm

Explanation

The length of a square is 494 cm.

Because the area is 244,036 cm² the length is √244,036 = 494.

Problem 2

Sarah is planning to paint her square garden wall of length 494 feet. The cost to paint a foot is 5 dollars. Then how much will it cost to paint the full wall?

Okay, lets begin

The length of the wall = 494 feet.

The cost to paint 1 square foot of wall = 5 dollars.

To find the total cost to paint, we find the area of the wall.

Area of the wall = area of the square = a²

Here a = 494

Therefore, the area of the wall = 494² = 494 × 494 = 244,036.

The cost to paint the wall = 244,036 × 5 = 1,220,180.

The total cost = 1,220,180 dollars

Explanation

To find the cost to paint the wall, we multiply the area of the wall by cost to paint per foot. So, the total cost is 1,220,180 dollars.
