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

Think of it as subtracting your adding a negative number to a positive, if the positive number is larger when adding, then your answer should end up positive if the negative number is larger your answer should be negative, in this case you could think of this problem as 5-2 instead of adding the 5 to the negative 2. so in this case your answer would be 3. if you don't get it try using a number line, those are very helpful when starting off!
