Answer:

x=12

Step-by-step explanation:

14/21=16/(x+12)

cross multiply

14(x+12)=16(21)

14x+168=336

14x=336-168

14x=168

x=12 (so the side would be x+12=24)

You could also see that 14 is 2/3 of 21, so 16 has to be 2/3 of x+12.  That means x+12 would have to equal 24.  If you take the 12 away from 24, x=12.
