Problem 1

Find the length of the square, where the area of the square is 16900 cm².

Okay, lets begin

The area of a square = a² So, the area of a square = 16900 cm² So, the length = √16900 = 130. The length of each side = 130 cm

Explanation

The length of a square is 130 cm.

Because the area is 16900 cm² the length is √16900 = 130.

Problem 2

Tom is planning to tile his square floor of length 130 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 = 130 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 = 130 Therefore, the area of the floor = 130² = 130 × 130 = 16900. The cost to tile the floor = 16900 × 5 = 84500. The total cost = 84500 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 84500 dollars.

Problem 3

Find the area of a circle whose radius is 130 meters.

Okay, lets begin

The area of the circle = 53066.8 m²

Explanation

The area of a circle = πr²

Here, r = 130

Therefore, the area of the circle = π × 130²

= 3.14 × 130 × 130

= 53066.8 m².

Problem 4

The area of the square is 16900 cm². Find the perimeter of the square.

Okay, lets begin

The perimeter of the square is 520 cm

Explanation

The area of the square = a²

Here, the area is 16900 cm²

The length of the side is √16900 = 130

Perimeter of the square = 4a

Here, a = 130

Therefore, the perimeter = 4 × 130 = 520.
