Answer 2

Answer:

The formula for finding the perimeter of a triangle is  P=a+b+c  where  a,b, and c  are the sides of the triangle. In this case, we can set  a=18 and b=20  for the given lengths and let  c  represent the third side. Inserting the given values to the perimeter of a triangle formula and solving for  c :

606060−3822=18+20+c=38+c=c=c  

So the length of the third side of the triangle is  20  cm.
