Problem 1

Find the length of a square, where the area of the square is 1,550,025 cm².

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

The area of a square = a²

 

So, the area of a square = 1,550,025 cm²

 

So, the length = √1,550,025 = 1245.

 

The length of each side = 1245 cm

Explanation

The length of a square is 1245 cm.

 

Because the area is 1,550,025 cm², the length is √1,550,025 = 1245.

Problem 2

Sarah is planning to tile her square patio of length 1245 feet. The cost to tile a foot is 6 dollars. Then how much will it cost to tile the full patio?

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

The length of the patio = 1245 feet

 

The cost to tile 1 square foot of patio = 6 dollars.

 

To find the total cost to tile, we find the area of the patio.

 

Area of the patio = area of the square = a²

 

Here a = 1245

 

Therefore, the area of the patio = 1245² = 1245 × 1245 = 1,550,025.

 

The cost to tile the patio = 1,550,025 × 6 = 9,300,150.

 

The total cost = 9,300,150 dollars

Explanation

To find the cost to tile the patio, we multiply the area of the patio by the cost to tile per foot. So, the total cost is 9,300,150 dollars.

Problem 3

Find the area of a circle whose radius is 1245 meters.

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

The area of the circle = 4,869,291.75 m²

Explanation

The area of a circle = πr²

 

Here, r = 1245

 

Therefore, the area of the circle = π × 1245² = 3.14 × 1245 × 1245 = 4,869,291.75 m².

Problem 4

The area of a square is 1,550,025 cm². Find the perimeter of the square.

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

The perimeter of the square is 4,980 cm.

Explanation

The area of the square = a²

 

Here, the area is 1,550,025 cm²

 

The length of the side is √1,550,025 = 1245

 

Perimeter of the square = 4a

 

Here, a = 1245

 

Therefore, the perimeter = 4 × 1245 = 4,980.
