Tolong cepat di jawab ya
Penjelasan dengan langkah-langkah:
1)
p = 8 satuan
l = 5 satuan
Keliling = 2 × (p + l)
Keliling = 2 × (8 + 5)
Keliling = 2 × 13
Keliling = 26 satuan
2)
p = 6 satuan
l = 4 satuan
Keliling = 2 × (p + l)
Keliling = 2 × (6 + 4)
Keliling = 2 × 10
Keliling = 20 satuan
3)
p = 6 satuan
l = 4 satuan
Keliling = 2 × (p + l)
Keliling = 2 × (6 + 4)
Keliling = 2 × 10
Keliling = 20 satuan
4)
p = 6 satuan
l = 1 satuan
Keliling = 2 × (p + l)
Keliling = 2 × (6 + 1)
Keliling = 2 × 7
