I would set up the problem so that the current dimensions become fractions:
9.5 cm wide/16 cm long; or 9.5/16
Compare that to the desired dimensions of:
x (unknown)/ 40 cm long; or x/40
Then Cross Multiply:
40 * (times) 9.5 = you got this!
16 * (times) x (or the unknown number)= 16x
The last step is to divide the two products:
you got this/16x
What you get is the unknown, or x. That's how wide it would be!
