Problem 1

Find the length of the side of a square, where the area of the square is 487,204 cm².

Okay, lets begin

The area of a square = a²

So, the area of a square = 487,204 cm²

So, the length = √487,204 = 698.

The length of each side = 698 cm

Explanation

The length of a square is 698 cm because the area is 487,204 cm². Therefore, the length is √487,204 = 698.

Problem 2

Sarah is planning to tile her square floor, which is 698 feet on each side. The cost to tile a foot is 5 dollars. How much will it cost to tile the entire floor?

Okay, lets begin

The length of the floor = 698 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 = 698

Therefore, the area of the floor = 698² = 698 × 698 = 487,204.

The cost to tile the floor = 487,204 × 5 = 2,436,020.

The total cost = 2,436,020 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 2,436,020 dollars.

Problem 3

Find the area of a circle whose radius is 698 meters.

Okay, lets begin

The area of the circle = 1,532,189.52 m²

Explanation

The area of a circle = πr²

Here, r = 698

Therefore, the area of the circle = π × 698²

= 3.14 × 698 × 698

= 1,532,189.52 m².

The perimeter of the square is 2,792 cm.

Explanation

The area of the square = a²

Here, the area is 487,204 cm²

The length of the side is √487,204 = 698

Perimeter of the square = 4a

Here, a = 698

Therefore, the perimeter = 4 × 698 = 2,792.
