If one of the parallel sides of a trapezoid (trapezium in the UK)
is 2.3 cm, the height is 15 cm and the area 600 sq.cm., what is
the length of the other parallel side?
   A = 

 600 = 

Multiply both sides by 2

1200 = (2.3 + b2)(15)

Divide both sides by 15

  80 = 2.3 + b2

Subtract 2.3 from both sides:

77.7 = b2

Answer: 77.7 cm
