1. Could somebody help me?

Ok so first you need to work out the total perimiter:

1. So on the bottom middle it's 10 metres long.

2. Left and right it's 6 each, so 6x2=12 then 12+10=22.

3. Then let's do the two four metre fence panels: 4x2=8 then 8+22=30.

4. Finally there's three 2-metre fence spots. So let's add them up. 3x2=6 then 6+30=36.

5. Now we know that the total perimiter is 36 metres. All we do now is divide that by 2 because we're buying fences that are two metres long.

ANSWER: 36/2=18. So we need 18 two metre fences.

Best regards again and goodluck!

Oh i'm very sorry didn't realise! I'll be sure to not do that in the future and i've deleted the previous post!

Ok I just read the forum rules, sorry about that! ;( Won't happen again!

Here's my NEW (and correct) answer:

OP, try to work out the whole perimiter of the fencing whilst remembering that there's already ten metres of wall so do NOT add that as part of the perimiter.

Then split your total perimiter by 2 in order to work out how many pieces of two metre fencing you're going to need!

Out of curiosity, may i ask why? Not challenging you or the team at all just curious as to the reasoning.

Best regards from me! FH
Not an issue, thanks for the coorperation. The OP is a little at fault as well, she should have posted some of her own thoughts/working out so we could nudge her through the problem.

The reason why is that prodding and plonking a student along helps them learn and develop their problem solving skills as well as ingraining some knowledge, not to mention that the person providing the hints grows mathematically from it as well. It's a little like a teacher-student situation, your teacher is never going to give you the full solution to the question on the first go you ask it, he/she will try and prod you along till you get there yourself because you learn so much more that way. Of course, there are times when after enough haggling has gone on where a full solution becomes beneficial, in which case, it's perfectly appropriate to post one. Not right at the onset though, obviously. Often, a small hint will get a student unstuck and they can work through the rest of the question, which imo, is far more beneficial than just copying off some answer off the internet. :-)

Best regards, Zacken.
