A regular pentagon has side length 12cm.the perimeter of the pentagon is 60cm and the area is 247.7cm2 .a second. Pentagon has side lengths equal to 24cm .find the perimeter of the second pentagon

To find the perimeter of the second pentagon, we need to know the number of sides it has. Since a regular pentagon has 5 sides, we can assume that the second pentagon is also a regular pentagon.

Given:
Side length of the second pentagon = 24 cm

To find the perimeter of a regular pentagon, we can use the formula:
Perimeter = number of sides × length of each side

Since the second pentagon is also a regular pentagon, the number of sides remains the same (5 sides).

Substituting the given values into the formula:
Perimeter = 5 × 24 cm

Perimeter = 120 cm

Therefore, the perimeter of the second pentagon is 120 cm.

To find the perimeter of the second pentagon, we need to determine the number of sides it has. Based on the information given, we know that a regular pentagon with side length 12 cm has a perimeter of 60 cm.

The formula to find the perimeter of a regular polygon is given by:

Perimeter = Number of Sides × Length of Each Side

Let's use this formula for the first pentagon with a side length of 12 cm and a perimeter of 60 cm:

60 cm = 5 × 12 cm

Now, we can use the same formula to find the perimeter of the second pentagon, given that it has side lengths equal to 24 cm:

Perimeter = Number of Sides × Length of Each Side

Let's assign the number of sides of the second pentagon as 'n' and the length of each side as 24 cm:

Perimeter of the second pentagon = n × 24 cm

Since both the pentagons are regular, they have the same number of sides. Therefore, the number of sides of the second pentagon is also 5.

Now, we can substitute these values into the formula:

Perimeter of the second pentagon = 5 × 24 cm

Calculating this value:

Perimeter of the second pentagon = 120 cm

Therefore, the perimeter of the second pentagon is 120 cm.

120

Since perimeter is a linear measurement, the ratio of their perimeters is the same as the ratio of their sides.

The sides are doubled, so their perimeter is doubled, namely 120 cm

or

so 12/24 = 60/x
12x = 1440
x = 1440/12 = 120
