1. The problem statement, all variables and given/known data Image is very big. Angles A and B are 120° length of metal is 5m width of metal is 0.6m it's an isosceles trapezoid drainage. 2. Relevant equations ° in a trapezoid: 180(n-2) A = 2(bh/2) + wh 3. The attempt at a solution I'm not sure, I started but I'm not even sure if I'm thinking of it right since the question is stated in a confusing way. This is what I believe I have to do so far. w = AD + AB + BC = 0.6 l = 2x + 2y = 5 x = z + 2b A = bh + wh I know it's really complicated but I'm not quite sure how to go about it, I'm just wondering if someone can tell me exactly what the question is asking and if I'm on the right track, thanks.
