The answer is 18 because to find the perimeter you have to add length+width+width+length so we know that the length is 25 so we add 25+25 which is 50. then we subtract 86-50 which is 36. so we do 36 divided by 2 which gets us 18. Hope this Helps! :)

Answer:
they are 16 and 4
Step-by-step explanation:
We can call the numbers x and y and we can write:
x - y = 12
x + y = 20
Adding these equations gives us 2x = 32 which means x = 16 and substituting this value into the first equation gives us y = 4.
