Answer:
The perimeter of the triangle is 138cm
Step-by-step explanation:
Let us assume that the ∆PLM is an equilateral triangle.
therefore, PQ = 1/2 LM
23 ×2 =46
therefore, LM = 46cm
perimeter of the∆ = PL + LM + PM
LM=PM= PL as it is an equilateral triangle
therefore, 46+46+46 =138
The perimeter of the∆ PLM = 138cm
