Question

Peter kept his pony in a rectangular paddock the perimeter of which was 240 metres and the area was 3200 square metres. What were the dimensions of the paddock?
you know that length + width = 120m
So just for grins, what are the factors of 32 which add up to 12?
Now, what are the factors of 3200 which add up to 120?
The factors of 32 are 8 and 4, since they add up to 12 anyways..
And so... the factors for 3200 are both 100 and 20 AND 40 and 80
wait.. where did 120metres come from?
sorry my head is a bit muddle up today... I would've been able to solve it
perimeter is 2(length+width)
