Problem 1

Find the length of the square, where the area of the square is 722,500 cm².

Okay, lets begin

The area of a square = a²

So, the area of a square = 722,500 cm²

So, the length = √722,500 = 850.

The length of each side = 850 cm

Explanation

The length of a square is 850 cm.

Because the area is 722,500 cm², the length is √722,500 = 850.

Problem 2

John is planning to tile his square room, which has a length of 850 feet. The cost to tile a foot is 5 dollars. How much will it cost to tile the entire room?

Okay, lets begin

The length of the room = 850 feet

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

To find the total cost to tile, we find the area of the room,

Area of the room = area of the square = a²

Here a = 850

Therefore, the area of the room = 850² = 850 × 850 = 722,500.

The cost to tile the room = 722,500 × 5 = 3,612,500.

The total cost = 3,612,500 dollars

Explanation

To find the cost to tile the room, we multiply the area of the room by the cost to tile per foot. So, the total cost is 3,612,500 dollars.

Problem 3

Find the area of a circle whose radius is 850 meters.

Okay, lets begin

The area of the circle = 2,268,150 m²

Explanation

The area of a circle = πr²

Here, r = 850

Therefore, the area of the circle = π × 850² = 3.14 × 850 × 850 = 2,268,150 m².
