Area and perimeter of a rectangle

Task

The program gets the length and width of a rectangle (whole numbers, each on its own line - reading them is already done). Calculate the area and the perimeter, store them in the variables obsah and obvod and print them like this (for length 7 and width 4):

Obsah: 28

Obvod: 22

Examples

Input
```
7
4
```
Expected output
```
Obsah: 28
Obvod: 22
```

After you submit, 4 hidden tests will also check your solution: a 1 × 1 square, larger numbers, zero width, the variables obsah and obvod.

You need to know

Python starts the first time you run code.

dlzka = int(input())
sirka = int(input())
# vypočítaj obsah a obvod a vypíš ich

Ctrl+Enter runs the program. Tab indents. Press Esc, then Tab, to leave the editor.

Input (stdin)

Each line = one call to input().
