Question

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?

Sum

Solution

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
