In the given figure, all triangles are equilateral and AB = 8 units. Other triangles have been formed by taking the mid points of the sides. What is the perimeter of the figure?
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
