This research has as main objective to analyze the errors made by students of a third year of high school, in a educational institution of Rio Grande do Sul, in calculating perimeters and areas of plane figures, to develop methodological strategy to overcome difficulties. As specific objectives, we proposed to: 1) detect and analyze the errors made by students; 2) interviewing teachers about the causes of the errors; 3) develop a product to assist students from high school to review the contents of perimeter and area. Research has qualitative character and was conducted with 22 students of a third year of high school, to which was applied a test composed of geometry questions on calculation of perimeters and areas. Also a questionnaire was applied to 25 teachers of basic education, who expressed their opinions about the causes of errors and strategies to overcome them. The literature review took into account texts on error analysis in general and on teaching geometry in particular. The error analysis was performed in three steps and the errors detected were analyzed and classified. Also teachers' responses were analyzed, indicating their opinions about the errors. Through the data collected, it was realized that the students who participated have many difficulties with elementary school content, especially algebraic manipulation and visualization of figures elements. On the opinions of the teachers about the most frequent categories of errors, most of them considered that the lack of attention, knowledge and interpretation of the issues are the causes of the errors found. As a product of this research, it was built a learning object that addresses the contents worked, perimeter and area of plane figures, with contextualized issues.
