Problem 1

Find the length of the square, where the area of the square is 488,601 cm².

Okay, lets begin

The area of a square = a²

So, the area of a square = 488,601 cm²

So, the length = √488,601 = 699.

The length of each side = 699 cm

Explanation

The length of a square is 699 cm. Because the area is 488,601 cm², the length is √488,601 = 699.

Problem 2

Sam is planning to paint his square wall of length 699 feet. The cost to paint a foot is 3 dollars. Then how much will it cost to paint the full wall?

Okay, lets begin

The length of the wall = 699 feet

The cost to paint 1 square foot of wall = 3 dollars.

To find the total cost to paint, we find the area of the wall,

Area of the wall = area of the square = a²

Here a = 699

Therefore, the area of the wall = 699² = 699 × 699 = 488,601.

The cost to paint the wall = 488,601 × 3 = 1,465,803.

The total cost = 1,465,803 dollars

Explanation

To find the cost to paint the wall, we multiply the area of the wall by the cost to paint per foot. So, the total cost is 1,465,803 dollars.

Explanation

The area of a circle = πr²

Here, r = 699

Therefore, the area of the circle = π × 699²

= 3.14 × 699 × 699

= 1,535,324.86 m².
