Question 992206: Two equal isosceles triangles with the length of the shortest side equal to 4. The perimeter is equivalent to six times the length of the shortest side of the triangles. Find the length of the longest side of the triangles.

Your perimeter seems to mean, for both triangles together.

Not clear is, which part of either triangle is to be shortest side of 4 units. Taking the longer side as x, then the perimeter sum is 2(4+2x).

2%282x%2B4%29=6%2A4

4x%2B8=24
x%2B2=6
x=4, but this would be equilateral, NOT isosceles.

The other possibility is that x should be the either of the equal side. The sum of perimeters would be 2%28x%2B2%2A4%29, and then the perimeter relationship would become 2%28x%2B2%2A4%29=6%2A4, six times the length of the shortest side of 4.

2x%2B16=24
x%2B8=12
x=4, still not what you want, still being equilateral.

Did you maybe have a mistake in the description?
