Remember that the formula to calculate the area of a trapezoid is equal to
[tex]A=\frac{1}{2}\cdot\lbrack b1+b2\rbrack\cdot h[/tex]In this problem
we have
b1=6cm
b2=6+2=8 cm
h=5 cm
substitute given values in the formula
[tex]\begin{gathered} A=\frac{1}{2}\cdot\lbrack6+8\rbrack\cdot5 \\ \\ A=\frac{1}{2}\cdot\lbrack14\rbrack\cdot5 \\ A=35\text{ cm2} \end{gathered}[/tex]
