Maths help. Pleaseeeeeeee??? :)?
When you have 2 triangular fields, they both have the same angles. All three lengths of fencing on both fields are a whole number of decametres. 2 of the side lengths are the same but the third one is different. One of the fields is the smallest it could be with a whole number of lengths. What is the length of that fence?

These are isosceles triangles and one is an enlargement of the other. With all the lengths being whole numbers the smallest triangle it could be is on with sides 2, 2 and 1, giving 5 decametres.
I don't quite see where the other triangle comes in? If it is an enlargement of the first, the smallest it could be with whole nubers is 4, 4 and 2, giving 10 decametres.
Hope this helps, or else I think a piece of information may be missing.
