PROGRAMMING:Calculate the area and perimeter of a regular pentagon
Input a number from the keyboard as the side length of the regular pentagon, calculate and output the perimeter and area of the regular pentagon.
The formula for calculating the area of regular pentagon is as follows:
S=$${a^2\times\sqrt{25+10\times\sqrt5}}/4$$
###Input format:
Enter the side length of the regular pentagon. For example:
five
###Output format:
Output the area and perimeter of a regular pentagon. The first line outputs area and the second line outputs perimeter. For example:
forty-three point zero one one nine
twenty-five
###Input example:
```in
sixteen point eight
```
###Output example:
```out
four hundred and eighty-five point five eight seven five
eighty-four
```
