Problem 1

Find the length of the square, where the area of the square is 1,545,049 cm².

Okay, lets begin

The area of a square = a²

So, the area of a square = 1,545,049 cm²

So, the length = √1,545,049 = 1243.

The length of each side = 1243 cm

Explanation

The length of a square is 1243 cm.

Because the area is 1,545,049 cm², the length is √1,545,049 = 1243.

Problem 2

Sarah is planning to paint her square garden wall of length 1243 feet. The cost to paint a foot is 2 dollars. Then how much will it cost to paint the full wall?

Okay, lets begin

The length of the wall = 1243 feet

The cost to paint 1 square foot of wall = 2 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 = 1243

Therefore, the area of the wall = 1243² = 1243 × 1243 = 1,545,049.

The cost to paint the wall = 1,545,049 × 2 = 3,090,098.

The total cost = 3,090,098 dollars

Explanation

To find the cost to paint the wall, we multiply the area of the wall by cost to paint per foot.

So, the total cost is 3,090,098 dollars.

Find the area of a circle whose radius is 1243 meters.

Okay, lets begin

The area of the circle = 4,854,521.94 m²

Explanation

The area of a circle = πr²

Here, r = 1243

Therefore, the area of the circle = π × 1243² = 3.14 × 1243 × 1243 = 4,854,521.94 m².
