# when i try to use the code let areaInMeters = area / 10.764, i get the error message stating: Binary operator '/' cannot

when i try to use the code let areaInMeters = area / 10.764, i get the error message stating: Binary operator '/' cannot be applied to operands of type 'Int and 'Double'

I think it wants the same type of number on both sides of the division. You've got Int / Double. If you decare your `area` to be a Double, this should be fine. You may be able to cast the int to a double, too.

This is down to 'strong typing' that Swift is very keen on.

I hope that helps.

let areaInMeeters = Double(area) / 10.764

Now I am using El Capitan Beta and Xcode 7 Beta but what work for me is as others suggested declaring area as a double.

let areaInMeters = Double(area) / 10.764

So basically when I divide things it has to be Int / Int, Double / Double, or Float / Float?

I think you need to think further than that. You need to think about what is receiving the result too - Int /Int may need the receiver to be expecting a Float as the result is relatively unlikely to be an Int unless we're losing loads of accuracy.

Ninyas' solution worked like a charm for me.

I get the exact same error, and it won't work no matter the suggestions made.
