To find the perimeters of a triangle you add the three sides together. if you get one of the two congruent sides you know the other congruent side. Then you use the pathagrium theorem to find the last side and add them up.
Pathagrium theorem= a square + b square = c square where c is the hypotenuse

If the base of an isosceles triangle is 11 and its perimeter is 39, then it has a height of 12.87.
How can you find the perimeter of isosceles triangle?
The answer depends on what information you have but, basically, you need to add together the lengths of the three sides of the triangle.
How do you find a perimeter of an isosceles triangle?
Assuming that neither of the sides of equal length is the base, Perimeter = Base + 2*Slanted sides.
