Problem 1

Find the length of the square, where the area of the square is 613,089 cm².

Okay, lets begin

The area of a square = a²

So, the area of a square = 613,089 cm²

So, the length = √613,089 = 783.

The length of each side = 783 cm

Explanation

The length of a square is 783 cm.

Because the area is 613,089 cm², the length is √613,089 = 783.

Problem 2

Sarah is planning to paint her square garden wall with a length of 783 feet. The cost to paint a foot is 4 dollars. Then how much will it cost to paint the full wall?

Okay, lets begin

The length of the wall = 783 feet

The cost to paint 1 square foot of wall = 4 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 = 783

Therefore, the area of the wall = 783² = 783 × 783 = 613,089.

The cost to paint the wall = 613,089 × 4 = 2,452,356.

The total cost = 2,452,356 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 2,452,356 dollars.
