The wedge contain 3 different rectangles and 2 congruent triangles.

Area of a triangle is

From the given figure it is clear that base of the both  triangles is 4 ft and height is 3 ft.

Area of a triangle is

Area of a rectangle is

Length and width of the first rectangle are 6 ft and 3 ft respectively. So, the area first rectangle is

Length and width of the second rectangle are 6 ft and 4 ft respectively. So, the area second rectangle is

Length and width of the third rectangle are 6 ft and 5ft respectively. So, the area third rectangle is

The total area of this wedge is

The area of wedge is 84 square ft.

Therefore, option 1 is correct.
