Problem 1

Find the side length of a square, where the area of the square is 1,333,025 cm².

Okay, lets begin

The area of a square = a²

So, the area of a square = 1,333,025 cm²

So, the length = √1,333,025 = 1155.

The length of each side = 1155 cm

Explanation

The length of a square is 1155 cm.

Because the area is 1,333,025 cm², the length is √1,333,025 = 1155.

Problem 2

Tom is planning to paint his square wall of length 1155 feet. The cost to paint a square foot is 3 dollars. Then how much will it cost to paint the full wall?

Okay, lets begin

The length of the wall = 1155 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 = 1155

Therefore, the area of the wall = 1155² = 1155 × 1155 = 1,333,025.

The cost to paint the wall = 1,333,025 × 3 = 3,999,075.

The total cost = 3,999,075 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 3,999,075 dollars.
