Maths trapeziums lengths help needed?

Question

Answer 1

The sides of trepezium a  = x  meters,

b  = 3x  meters

c  = 2x  meters 

d  = 3x  meters

Perimeter of trepezium P  = a  + b  + c  + d

P  = 108 meters

108 = x  + 3x  + 2x  + 3x

108 = 9x

x  = 108/9

x  = 12 meters.

Sides of trepezium a  = 12 meters , b  = 36 meters , c  = 24 meters and d = 36 meters.
