Geometry is a branch of mathematics taught at all levels of education. One of the foundations in understanding geometry is flat shapes, especially combined flat shapes. However, students' ability to solve combined flat-shape problems requires special attention. This research will look at students' abilities in solving combined flat shape problems, to describe students' abilities in applying the concepts of area and perimeter of combined flat shapes. Qualitative descriptive methods will be used to examine this research. The research will be carried out at one of the Junior High Schools (SMP) in Karawang Regency, with research subjects consisting of 15 class IX students. Data will be collected through a written test taken from the 2013 Curriculum Package Book (Mathematics) 2017 Revised Edition with 3 questions. From the results of this research, it was concluded that students' ability to solve combined flat-shape problems was considered quite good. This can be seen from the written test where the majority of students have understood the concept of combined plane shapes by following the appropriate processing steps and showing expertise in mathematical calculations. However, most students are still unable to identify information at the beginning of the problem. Therefore, a little effort is needed to develop students' abilities in solving problems, especially in identifying information.

This research aims to determine the effectiveness of the Problem Based Learning (PBL) model on the ability to solve addition problems in class I mathematics material at SDN Gajahmungkur 04. This type of research uses a quantitative research approach with an experimental method with a Pre-Experimental Design in the form of One Group Pretest Posttest. The sample of this research was 27 students. The results of this research are proven by the n-gain score of 0.4047 in the medium category. Then test normality with the Shapiro Wilk test on the pretest and posttest data. It can be seen from the normality test obtained, namely if the significance value is 0.074 > 0.05 then the data on the pretest is normal. Meanwhile, the posttest results were significant 0.106 > 0.05, including normal. The effectiveness test using the paired sample t-test showed that the significance value (sig.) was 0.000 or it could be said that the sig. < 0.05 (Ha accepted) which means there is a significant difference between the pretest and posttest scores. This shows the effectiveness of the problem based learning model on students' problem solving abilities. Based on the research results, it can be concluded that the problem based learning model is effective for problem solving abilities.
