Pereti

#2251

Localitatea Târgovişte este în plină modernizare. Primăria decide să inventarieze toate clădirile din oraş pentru a renova faţadele acestora. În acest sens analizează harta oraşului şi constată că toţi pereţii sunt aşezaţi doar pe direcţia Nord Sud sau Est Vest. Pereţii vizibili de către turiști sunt doar aceia la care se poate ajunge din exteriorul orașului prin deplasarea pe cele două direcţii date, în oricare din cele patru sensuri (N, E, S, V). Harta oraşului este întocmită pe un caroiaj format din pătrate cu latura 1. Cunoscându-se harta oraşului, determinaţi lungimea pereţilor vizibili ce urmează a fi zugrăviţi.
