Functions for a rectangle

Task

Write two functions:

obvod_obdlznika(a, b) returns the perimeter of a rectangle with sides a and b,
obsah_obdlznika(a, b) returns its area.

The functions must return the result with return, not print it. The tests call them with various sides.

Examples

Call

print(obvod_obdlznika(7, 4), obsah_obdlznika(7, 4))

Expected output

22 28

After you submit, 4 hidden tests will also check your solution: a 1 × 1 square, a decimal side, a zero side, the result is returned, not printed.

You need to know

Python starts the first time you run code.

def obvod_obdlznika(a, b):
    pass
def obsah_obdlznika(a, b):
    pass
# Kód pod touto podmienkou sa spustí, keď program spustíš ty. Testy ho preskočia
# a tvoje funkcie zavolajú priamo.
if __name__ == "__main__":
    print(obvod_obdlznika(7, 4))
    print(obsah_obdlznika(7, 4))

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

Input (stdin)

Each line = one call to input().

Hints

Try it yourself first. Each hint reveals a little more - and lowers the reward a little.

Signed out, hints are free - but no XP is awarded either.

Solution

The solution unlocks after the last hint.
