Answer:

  • 200.33 m

Step-by-step explanation:

Let the amount of shirt material is s and trouser material is t.

We have equations based on given details:

  • s/t = 3/2
  • s*50*(1 + 0.12) + t*90*(1 + 0.1) = 36660

Simplify and solve for t by substitution:

  • s = 3/2t
  • 56s + 99t = 36660
  • 56*3/2t + 99t = 36660
  • 84t + 99t = 36660
  • 183t = 36660
  • t = 36660/183
  • t = 200.33 m
