Given:
The bases of trapezoid are, a = 8 m, b = 11 m.
The height is, h = 12 m.
The expression for calculating the area of a trapezoid is given by,
[tex]A=\frac{a+b}{2}h[/tex]Substituting the values, we get,
[tex]A=\frac{11+8}{2}\times12=\frac{19}{2}\times12=19\times6=114m^2[/tex]Thus, the area is 114 sq m.
