The lateral area is the area of everything but the base.  A shortcut formula for this area is Ph.  (where P is the perimeter of the base and h is the height of the prism).
So the lateral area is (3+9+9.49)x37 = 795.13 m^2  or 795 m^2
The surface area is the lateral area plus the area of the 2 bases.  The base is a triangle.  (area = 1/2 bh) 
Since there are two identical bases, the total area of the base is just 3x9 = 27
So the surface area is 795.13 + 27 = 822.13 m^2 or 822 m^2.
