Call the two sides of the window H for height. Call the top and bottom W for width.

Given the top light is an equilateral triangle, all three sides are equal,

and given the base forms the top width of the window; the sides must also = W.

So we have (2 x H) + (4 x W) = 6 meters.

I have 2 unknowns and only 1 equation so if I understand the question correctly,

we are missing a set of constraints that will give us a second equation.

Is there more to it you might have missed in the problem?
