4. 30dm
5. 78cm
Step-by-step explanation:
1. Perimeter of the square = 4cm + 4cm + 4cm + 4cm = 16cm
2. Perimeter = 8dm + 8dm + 5dm + 5dm
= 26dm
3. Perimeter of rectangle = 3mm + 3mm + 7mm + 7mm = 20mm
4. Perimeter of triangle = 8dm + 12dm + 10dm = 30dm
5. Perimeter = 23cm + 23cm + 16cm + 16cm = 78cm
