Max Maths, Year 6, Try it, Perimeters of compound shapes (2)

In the 'Max Maths, Year 6' curriculum, students are challenged to calculate the perimeters of compound shapes, which are shapes made up of two or more simple shapes joined together. In a particular exercise, they are given a compound shape with various lengths marked on its edges. The task is to find the total perimeter of the shape by adding together the lengths of all its sides. The shape is labeled with points A to F, and the lengths between certain points are given in centimeters. For example, the length from point A to B might be 3 cm, B to C 5 cm, and so on.

To solve the problem, students must identify the lengths of all the sides, including those that are not directly labeled. They may need to perform subtraction or addition to find missing lengths, as indicated by placeholders such as "C = cm – cm" and "F = cm + cm". Once all individual side lengths are determined, the students add them up to find the total perimeter of the shape. The exercise provides a structured approach by listing out each side's length followed by a space for the calculated total perimeter, which is the sum of all the individual lengths. This exercise helps to reinforce the students' understanding of perimeters and how to work with compound shapes.
