Problem 1

Find the length of the square, where the area of the square is 109,561 cm².

Okay, lets begin

The area of a square = a²

So, the area of a square = 109,561 cm²

So, the length = √109,561 = 331.

The length of each side = 331 cm

Explanation

The length of a square is 331 cm. Because the area is 109,561 cm², the length is √109,561 = 331.

Problem 2

Lisa is planning to tile her square floor of length 331 feet. The cost to tile a foot is 5 dollars. Then how much will it cost to tile the full floor?

Okay, lets begin

The length of the floor = 331 feet

The cost to tile 1 square foot of 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 = 331

Therefore, the area of the floor = 331² = 331 × 331 = 109,561.

The cost to tile the floor = 109,561 × 5 = 547,805.

The total cost = 547,805 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 547,805 dollars.

Problem 3

Find the area of a circle whose radius is 331 meters.

Okay, lets begin

The area of the circle = 344,360.78 m²

Explanation

The area of a circle = πr²

Here, r = 331

Therefore, the area of the circle = π × 331² = 3.14 × 331 × 331 = 344,360.78 m².

Problem 4

The area of the square is 109,561 cm². Find the perimeter of the square.

Okay, lets begin

The perimeter of the square is 1,324 cm.

Explanation

The area of the square = a²

Here, the area is 109,561 cm²

The length of the side is √109,561 = 331

Perimeter of the square = 4a

Here, a = 331

Therefore, the perimeter = 4 × 331 = 1,324.
