Problem 1

Find the length of the square, where the area of the square is 183,184 cm².

Ray, the Boy Character from BrightChamps Saying "Let’s Begin"

The area of a square = a²

 

So, the area of a square = 183,184 cm²

 

So, the length = √183,184 = 428.

 

The length of each side = 428 cm

Explanation

The length of a square is 428 cm. Because the area is 183,184 cm² the length is √183,184 = 428.

Problem 2

Lily is planning to paint her square wall of length 428 feet. The cost to paint a foot is 3 dollars. Then how much will it cost to paint the full wall?

Ray, the Boy Character from BrightChamps Saying "Let’s Begin"

The length of the wall = 428 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 = 428

 

Therefore, the area of the wall = 428² = 428 × 428 = 183,184.

 

The cost to paint the wall = 183,184 × 3 = 549,552.

 

The total cost = 549,552 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 549,552 dollars.

Problem 3

Find the area of a circle whose radius is 428 meters.

Ray, the Boy Character from BrightChamps Saying "Let’s Begin"

The area of the circle = 575,530.24 m²

Explanation

The area of a circle = πr²

 

Here, r = 428

 

Therefore, the area of the circle = π × 428² = 3.14 × 428 × 428 = 575,530.24 m².

Problem 4

The area of the square is 139,600 cm². Find the perimeter of the square.

Ray, the Boy Character from BrightChamps Saying "Let’s Begin"

The perimeter of the square is 1,496 cm.

Explanation

The area of the square = a²

 

Here, the area is 139,600 cm²

 

The length of the side is √139,600 = 374

 

Perimeter of the square = 4a

 

Here, a = 374

 

Therefore, the perimeter = 4 × 374 = 1,496 cm.
