The lengths of lines KO and LN is; 24cm and 18m respectively.

Equilateral triangles

Since the face of the building is an equilateral triangle and the sections of reinforcement are parallel to side JP;

  • In essence; MJ = JP = PM

  • Similarly, MK = KO = OM

  • and ML = LN = NM

On this note, since, MK = 18m +6m = 24m.

  • It follows that, KO = 24cm

Similarly, since, ML = 18m

  • It follows that, LN = 18cm
