Problem 1

Find the length of the square, where the area of the square is 262,144 cm².

Okay, lets begin

The area of a square = a²

So, the area of a square = 262,144 cm²

So, the length = √262,144 = 512.

The length of each side = 512 cm

Explanation

The length of a square is 512 cm.

Because the area is 262,144 cm² the length is √262,144 = 512.

Problem 2

Anna is planning to paint her square wall of length 512 feet. The cost to paint a foot is 2 dollars. Then how much will it cost to paint the full wall?

Okay, lets begin

The length of the wall = 512 feet

The cost to paint 1 square foot of wall = 2 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 = 512

Therefore, the area of the wall = 512² = 512 × 512 = 262,144.

The cost to paint the wall = 262,144 × 2 = 524,288.

The total cost = 524,288 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 524,288 dollars.
