The first thing you do is cross multiply which is 3/4x=48 (3/4 = 0.75). Therfore you divide each side by .75. The left side cancels out. For the right side you divide 48 by .75 and gives you 64. x=64
        
             
        
        
        
It seemed like it should have been so simple. There was nothing inherently difficult with getting the project done.

Answer:
486 mm
Step-by-step explanation:
solve each side on it's own first
First 2 rectangles: 288 mm all together
2 rectangle: 144 mm
Triangles: 54 mm
Then add rectangles and triangles:
288 mm + 144 mm + 54 mm = 486 mm
 
        
             
        
        
        
They are all vertical angles.
