Answer:

[tex]4.4cm[/tex]

Step-by-step explanation:

[tex]area \\ 9.9 = \frac{1}{2} \times (a + b) \times h \\ 9.9 = \frac{1}{2} \times (2 + 2.5) \times h \\ 9.9 = \frac{1}{2} \times 4.5 \times h \\ 9.9 = \frac{4.5h}{2} \\ 9.9 = 2.25h \\ \frac{9.9}{2.25} = \frac{2.25h}{2.25} \\ h = 4.4 \: \: cm[/tex]
