Answer:
76m
Step-by-step explanation:
Since you know that two of the sides equal 97m, both of those sides equal 194m.
Then you can find the length of the other two sides: 346(total length of all sides) - 194 = 152(sum of both of the other sides)
Divide the sum of the unknown sides (152) by 2 to find out what those sides equal (76)
