To find the perimeter of a equilateral triangle with a missing side;
The missing side is equal to the sides given hence to calculate the perimeter you add all of the sides.
To find the perimeter of a scalene triangle with a missing side:
You need to use the formula a²+b²=c² where a and b represent the sides given and c to represent the missing side.
Plug in your known sides, square them and add. then find the square root of the sum to find the value of c.
c=√(a²+b²)
To get the perimeter you add now all the three sides
