The length of the missing side of the triangle is 6 cm.
A triangle is a polygon with three sides and three angles. Types of triangles are isosceles, equilateral, obtuse and scalene triangle.
The perimeter of a triangle is the sum of all the sides of the triangle. Let x represent the missing length. Also, let the other sides be 3 cm and 10 m.
