Problem 1

Find the length of the square, where the area of the square is 2500 cm².

Okay, lets begin

The area of a square = a²

So, the area of a square = 2500 cm²

So, the length = √2500 = 50.

The length of each side = 50 cm

Explanation

The length of a square is 50 cm. Because the area is 2500 cm², the length is √2500 = 50.

Problem 2

Linda is planning to paint her square garden of length 50 feet. The cost to paint a foot is 4 dollars. Then how much will it cost to paint the full garden?

Okay, lets begin

The length of the garden = 50 feet

The cost to paint 1 square foot of garden = 4 dollars.

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

Area of the garden = area of the square = a²

Here a = 50

Therefore, the area of the garden = 50² = 50 × 50 = 2500.

The cost to paint the garden = 2500 × 4 = 10000.

The total cost = 10000 dollars

Explanation

To find the cost to paint the garden, we multiply the area of the garden by cost to paint per foot. So, the total cost is 10000 dollars.

Problem 3

Find the area of a circle whose radius is 50 meters.

Okay, lets begin

The area of the circle = 7850 m²

Explanation

The area of a circle = πr²

Here, r = 50

Therefore, the area of the circle = π × 50²

= 3.14 × 50 × 50

= 7850 m².

Problem 4

The area of the square is 2500 cm². Find the perimeter of the square.

Okay, lets begin

The perimeter of the square is 200 cm.

Explanation

The area of the square = a²

Here, the area is 2500 cm²

The length of the side is √2500 = 50

Perimeter of the square = 4a

Here, a = 50

Therefore, the perimeter = 4 × 50 = 200.

Problem 5

Find the square of 51.

Okay, lets begin

The square of 51 is 2601.

Explanation

The square of 51 is multiplying 51 by 51. So, the square = 51 × 51 = 2601.
