Answer:

1. 16cm

2. 26dm

3. 20mm

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

Hope it is helpful...
