Abstract: This study aimed to describe the types of errors made by class VII students in solving the story question in on area and perimeter of two-dimentional figure material.The type of the research was a qualitative research.The subjects were 3 students drawn from 24 students of class VII SMP Al-Azhar Mandiri Palu.The results indicated that the errors made by students were conceptual errors and procedural errors. Conceptual errors that the students made include (1) a misconception that students were incorrect in using the formula of the area and perimeter as well as incorrect in understanding the story question, (2) errors of fact that incorrect or did not write area and perimeter units in the problem solution, and, (3) error principles that could not change the story question into mathematical models.
