A rectangle with height 4 and width w contains three circles as in the diagram, all tangent to the rectangle and to each other. What is w?

Well then the largest circle must have diameter 4, since it's from one side to the other, and the other small ones, being equal, must have 4/2 diameters. 4+2 = 6

w = 6.

If you don't understand anything feel free to ask!
