Solution :

\begin{gathered}\bf = > \: area \: = \: \frac{1}{2} \times \: ( \: sum \: of \: bases \: ) \: \times \: height \\ \\ = > \bf \: 65 \: = \: \frac{1}{2} \: \times \: 39 \: \times \: h \\ \\ = > \bf \: h \: = \: \frac{65 \: \times \: 2}{39} \\ \\ = > \bf \: h \: = \: 3.33 \: cm \:\end{gathered}=>area=21×(sumofbases)×height=>65=21×39×h=>h=3965×2=>h=3.33cm
