Problem 1

Find the length of the square where the area of the square is 3,240,000 cm².

Okay, lets begin

The area of a square = a²

So, the area of a square = 3,240,000 cm²

So, the length = √3,240,000 = 1800.

The length of each side = 1800 cm

Explanation

The length of a square is 1800 cm.

Because the area is 3,240,000 cm², the length is √3,240,000 = 1800.

Problem 2

Lisa is planning to tile her square floor with a side length of 1800 feet. The cost to tile a square foot is 5 dollars. How much will it cost to tile the entire floor?

Okay, lets begin

The length of the floor = 1800 feet

The cost to tile 1 square foot of the floor = 5 dollars.

To find the total cost to tile, we find the area of the floor.

Area of the floor = area of the square = a²

Here a = 1800

Therefore, the area of the floor = 1800² = 1800 × 1800 = 3,240,000.

The cost to tile the floor = 3,240,000 × 5 = 16,200,000.

The total cost = 16,200,000 dollars

Explanation

To find the cost to tile the floor, we multiply the area of the floor by the cost to tile per foot. So, the total cost is 16,200,000 dollars.

Problem 3

Find the area of a circle whose radius is 1800 meters.

Okay, lets begin

The area of the circle = 10,178,400 m²

Explanation

The area of a circle = πr²

Here, r = 1800

Therefore, the area of the circle = π × 1800² = 3.14 × 1800 × 1800 = 10,178,400 m².

Problem 4

The area of the square is 3,240,000 cm². Find the perimeter of the square.

Okay, lets begin

The perimeter of the square is

Explanation

The area of the square = a²

Here, the area is 3,240,000 cm²

The length of the side is √3,240,000 = 1800

Perimeter of the square = 4a

Here, a = 1800

Therefore, the perimeter = 4 × 1800 = 7,200 cm.

Problem 5

Find the square of 1801.

Okay, lets begin

The square of 1801 is 3,242,401

Explanation

The square of 1801 is found by multiplying 1801 by 1801. So, the square = 1801 × 1801 = 3,242,401
