उत्तर
We have given, all the triangles are equilateral and AB = 8 units
Now, perimeter of the given figure = AE + EF + FC + GH + HI + ID + DC + CK + KN + NO + OM + ML + LJ + JB + BU + US + SR + RT + TQ + QP + PA
= (4 + 2 + 1 + 1 + 1 + 2 + 4 + 4 + 2 + 1 + 1 + 1 + 2 + 4 + 4 + 2 + 1 + 1 + 1 + 2 + 4) units
= 45 units
