Topological indices are numerical parameters of a graph which characterize its topology and are usually graph invariant. In QSAR/QSPR study, physico-chemical properties and topological indices such as Randić, atom-bond connectivity ABC and geometric-arithmetic (GA) index are used to predict the bioactivity of chemical compounds. Graph theory has found a considerable use in this area of research. In this paper, we study and derive analytical closed results of general Randić index RG, Boron triangular sheet BTSmn, Borophene chain of B36n and Melem chain nanotube MCn. We also compute the general first Zagreb, ABC, GA, ABC4 and GA5 indices for sheet and chains for the first time and give closed formulas of these degree based indices.
