Answer: 48 meters
we already know that one side is 50 m, so since it's a 
rectangle you can multiply 50 by 2 which gives you 100. Know you have two sides left (which would be the same number) . You can do it easy and subtract 196 and 100 which gives you 96. Then, divide 96 by 2 and you get 48. 
---- check: do 48(2)+50(2) it will give you 196
