Area Decomposition (B) WORKSHEET
Area Decomposition (B) WORKSHEET DESCRIPTION
This worksheet, split into two sections, requires students to find the area and perimeter of compound shapes made up of triangles and rectangles.
Section A asks students to find the perimeter of six different shapes. Learners will have to remember to include all lengths, even those without labels. However, no calculation of unknown lengths is necessary.
In section B, students will find the area of six compound shapes. We guide students through the process of dividing the shape into rectangles and triangles in order to complete their calculations. Some missing lengths will have to be solved for before the area can be found.
All worksheets are created by the team of experienced teachers at Cazoom Math.
