Is ã13 supposed to mean √13 ?
Is the garden a rectangle?
If so, isn't the perimeter just the sum of the 4 sides?

Is ã13 supposed to mean √13 ?
yes and yes

So let's just add them up
√13 + √13 + 7√13 + 7√13
= 16√13

BTW, I get the square root sign on my PC by holding down the Alt key and while it is held down, on the number pad I pres 251, then release the Alt key

There are many such symbols that you can create that way, just try different combinations and make yourself a list.
