Sagot :
1. 44cm
Solution:
- P = L + L + W + W
- P = 15 + 15 + 7 + 7
- P = 44cm
2. 26cm
Solution:
- P = A + B + C
- P = 8 + 8 + 10
- P = 26cm
3. 32cm
Solution:
- P = s + s + s + s
- P = 8 + 8 + 8 + 8
- P = 32cm
4. 57m
Solution:
- P = A + B + C
- P = 17 + 17 + 23
- P = 57m
5. 69cm
Solution:
- P = A + B + C + D
- P = 24 + 27 + 9 + 9
- P = 69cm
Remember that when solving for perimeter you just need to add all sides.
