Answer:

96 square units

Step-by-step explanation:

Add the areas of all of the polygons in the area net which represent the sides of the triangular prism:

SA = 2 small rectangles + 1 big rectangle + 2 small triangles

SA = 2(3 * 7) + (6 * 7) + (6 * 2)

= 42 + 42 + 12

= 84 + 12

= 96 square units
