Ici, P = 2 × (12 + 5) = 2 × 17 = 34 cm.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0,"_debug_answer_data_type":"string","_debug_answer_data_preview":"{\"correct\": \"a\", \"options\": {\"a\": \"34 cm\", \"b\": \"60 cm\", \"c\": \"24 cm\", \"d\": \"29 cm\"}}","_debug_options_count":4},{"id":78408,"question":"Vrai ou Faux ? La somme de deux nombres pairs est toujours paire.","option_a":"Vrai","option_b":"Faux","option_c":"","option_d":"","option_e":"","option_f":"","bonne_reponse":"a","explication":"Vrai. Par exemple, 4 + 6 = 10 (pair).
