Since triangles ABC and DEP are equal, their sides will be equal. Therefore AB = DE = 3 centimeters, BC = EP = 4 centimeters, CA = PD = 5 centimeters.
The perimeter of a triangle is the sum of the lengths of all sides. So the perimeter of the triangle is DEP = DE + EP + PD = 3 cm + 4 cm + 5 cm = 7 cm + 5 cm = 12 centimeters.
Answer: 12 centimeters.
