Short Answer h = 6.5
Remark
I'm taking it that AB = 2.5 cm and that CD =  4cm

Formula
Area = 1/2(b1 + b2) * h

Givens
Area = 6.5 cm^2
b1 = 2.5 cm
b2 = 4 cm

Substitute
6.5 = 1/2 ( 2.5 + 4) * h
6.5 = 1/2 (6.5) * h              Multiply both sides by 2
6.5 * 2 = 6.5 * h                 Divide both sides by 6.5
6.5 * 2/ 6.5 = 6.5 * h / 6.5  
2 = h <<<<<< Answer
