Problem 1

Find the length of the square, where the area of the square is 1,265,625 cm².

Okay, lets begin

The area of a square = \(a^2\) So, the area of a square = 1,265,625 cm² So, the length = \(\sqrt{1,265,625} = 1125\). The length of each side = 1125 cm

Explanation

The length of a square is 1125 cm.

Because the area is 1,265,625 cm², the length is \(\sqrt{1,265,625} = 1125\).

Problem 2

Sarah is planning to carpet her square room of length 1125 feet. The cost to carpet a foot is 5 dollars. How much will it cost to carpet the full room?

Okay, lets begin

The length of the room = 1125 feet The cost to carpet 1 square foot of the room = 5 dollars. To find the total cost to carpet, we find the area of the room, Area of the room = area of the square = \(a^2\) Here \(a = 1125\) Therefore, the area of the room = \(1125^2 = 1125 × 1125 = 1,265,625\). The cost to carpet the room = 1,265,625 × 5 = 6,328,125. The total cost = 6,328,125 dollars

Explanation

To find the cost to carpet the room, we multiply the area of the room by the cost to carpet per foot.

So, the total cost is 6,328,125 dollars.

Problem 3

Find the area of a circle whose radius is 1125 meters.

Okay, lets begin

The area of the circle = 3,976,875 m²

Explanation

The area of a circle = \(\pi r^2\)

Here, \(r = 1125\)

Therefore, the area of the circle = \(\pi × 1125^2\) = 3.14 × 1125 × 1125 = 3,976,875 m².

Problem 4

The area of the square is 1,265,625 cm². Find the perimeter of the square.

Okay, lets begin

The perimeter of the square is 4500 cm.

Explanation

The area of the square = \(a^2\)

Here, the area is 1,265,625 cm²

The length of the side is \(\sqrt{1,265,625} = 1125\)

Perimeter of the square = 4a

Here, \(a = 1125\)

Therefore, the perimeter = 4 × 1125 = 4500 cm.
