Im confused what the question is...
Answer:
No; the slopes of segment EF and segment DF are not opposite reciprocals.
Step-by-step explanation:
The slope between two points O(e, f) and X (g,h) is given as:

The slopes of segment EF and segment DF are given below:

For triangle DEF to be a right triangle, DF and EF are supposed to be perpendicular to each other. Two line are said to be perpendicular if the product of their slope is -1, i.e the slope of one line is the negative reciprocal (opposite reciprocal) of the other line.
Since the slope of DF and EF are not opposite reciprocals, ΔDEF is not a right triangle.

Answer:
116
Step-by-step explanation:
∆ABC
A = ½bh = ½ × 12 × 6 = 36
∆ACD
A = ½bh = ½ × 16 × 7 = 56
∆ADE
A = ½bh = ½ × 16 × 3 = 24
ABCDE
A = ∆ABC + ∆ACD +∆ADE = 36 + 56 + 24 = 116
The area of the figure is 116 square units.
