Max Maths, Year 6, Try it, Perimeters of compound shapes (1)

In a mathematics exercise designed for Year 6 students, they are tasked with calculating the perimeter of compound shapes, starting with a real-world example. The question presents Padma's computer, which has a width of 22 cm and a length of 30 cm. Students are required to apply their understanding of perimeters to determine the total distance around Padma's computer. The formula provided to help students calculate the perimeter is P = (2 × width) + (2 × length).

Using the formula, students substitute the given dimensions of the computer into the equation. This results in P = (2 × 22 cm) + (2 × 30 cm), which simplifies to 44 cm + 60 cm. Adding these two sums together yields the final perimeter of the computer, which is 104 cm. This exercise reinforces students' skills in multiplication and addition, and it also provides practical application of these mathematical operations in finding the perimeters of rectangular objects.
