Problem 1

Find the length of the square, where the area of the square is 3249 cm².

Okay, lets begin

The area of a square = a²

So, the area of a square = 3249 cm²

So, the length = √3249 = 57.

The length of each side = 57 cm

Explanation

The length of a square is 57 cm. Because the area is 3249 cm², the length is √3249 = 57.

Problem 2

Sarah wants to carpet her square living room with a side of 57 feet. The cost to carpet a foot is 5 dollars. How much will it cost to carpet the full living room?

Okay, lets begin

The length of the living room = 57 feet

The cost to carpet 1 square foot = 5 dollars.

To find the total cost to carpet, we find the area of the living room,

Area of the living room = area of the square = a²

Here a = 57

Therefore, the area of the living room = 57² = 57 × 57 = 3249.

The cost to carpet the living room = 3249 × 5 = 16245.

The total cost = 16245 dollars

Explanation

To find the cost to carpet the living room, we multiply the area by the cost to carpet per foot. So, the total cost is 16245 dollars.

Problem 3

Find the area of a circle whose radius is 57 meters.

Okay, lets begin

The area of the circle = 10,207.34 m²

Explanation

The area of a circle = πr²

Here, r = 57

Therefore, the area of the circle = π × 57²

= 3.14 × 57 × 57

= 10207.34 m².
