Calculating the perimeters of shapes in m and cm

Maths

5cm and 2 mm > 5cm and 3 mm > 5 cm and 9 mm

5cm and 3 mm > 5cm and 2 mm > 5 cm and 1 mm

5cm and 3 mm > 5cm and 2 mm > 5 cm and 9 mm

9cm and 1 mm > 9cm and 9 mm > 9 cm and 7 mm

9cm and 7 mm > 9cm and 1 mm > 9 cm and 9 mm

9cm and 9 mm > 9cm and 7 mm > 9 cm and 1 mm

2cm and 1mm > 2cm and 70 cm > 2cm and 90 mm

2cm and 70 cm > 2cm and 1 mm > 2cm and 90 mm

2cm and 90 cm > 2cm and 1 mm > 2cm and 70 mm

2cm and 90 cm > 2cm and 70 mm > 2cm and 1 mm

70cm and 10mm < 70cm and 1 mm < 70cm and 9 mm

70cm and 1mm < 70cm and 10 mm < 70cm and 9 mm

70cm and 1mm < 70cm and 9 mm < 70cm and 10 mm

70cm and 9 mm < 70cm and 10 mm < 70cm and 1 mm
