Daily Challenge #281 - Area or Perimeter

#challenge

You are given the length and width of a 4-sided polygon. The polygon can either be a rectangle or a square.

If it is a square, return its area. If it is a rectangle, return its perimeter.

area_or_perimeter(6, 10) --> 32
area_or_perimeter(4, 4) --> 16

Tests

area_or_perimeter(5, 5)
area_or_perimeter(10, 20)

Good luck!

Here is the simple solution with Python:

def area_or_perimeter(l , w):
    if l == w:
        return l * w
    return (l + w) * 2

In js: let area_or_perimeter = (x, y) => x === y ? x*y : 2*(x+y);

Pass all the tests.

In Kotlin it would be:

fun area_or_perimeter(a: Int, b: Int) =
        if (a == b)
            a * b
        else
            2 * (a + b)

It's quite simple, check whether a=b if it's true return a*b if it's not, return (a+b)*2.
