Answer 1

notice, the prism is just 2 triangles and 3 rectangles
thus
find the area of the triangles, and the area of the rectangles
and sum them up, that'd be the area of the prism

Answer 2

look at your picture
the base, and the altitude or height of the triangle

recall that to get the area of a triangle is 1/2 * base * height
