Problem 1

Find the length of the square, where the area of the square is 426409 cm².

Okay, lets begin

The area of a square = a²

So, the area of a square = 426409 cm²

So, the length = √426409 = 653.

The length of each side = 653 cm

Explanation

The length of a square is 653 cm.

Because the area is 426409 cm², the length is √426409 = 653.

Problem 2

Tom is planning to paint his square wall of length 653 feet. The cost to paint a foot is 3 dollars. Then how much will it cost to paint the full wall?

Okay, lets begin

The length of the wall = 653 feet

The cost to paint 1 square foot of wall = 3 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 = 653

Therefore, the area of the wall = 653² = 653 × 653 = 426409.

The cost to paint the wall = 426409 × 3 = 1279227.

The total cost = 1279227 dollars

Explanation

To find the cost to paint the wall, we multiply the area of the wall by the cost to paint per foot. So, the total cost is 1279227 dollars.
