Find the perimeter of a triangular gusset with a base length of 170mm and the sides of 92mm and 193.3mm.
The formula for the perimeter (P) of a triangle is P = a + b + c (where a, b and c are the lengths of the three sides)
Substitute a, b and c with the measurements from this triangle.
P = 170 + 92 + 193.3
Add the side lengths together.
170 + 92 + 193.3 = 455.3
P=455.3mm
