To find the bottom edge as the image asks:
The "orange" in the image I attatched
The lines / hash marks let us know there are congruent sides to this shape.
-> See attatched.
Before we find the bottom edge, we need to turn 0.5 ft into inches.
One foot = 12 inches
Half a foot = 6 inches
Now, we add up the 3 inches from the left side, the 3 inches from the right side, and the 6 inches from the center.
6 + 3 + 3 = 12 inches
The bottom edge is 12 inches.

To find the total perimeter as you ask in the text part:
The lines / hash marks let us know there are congruent sides to this shape.
-> See attatched.
Before we find the perimeter, we need to turn 0.5 ft into inches.
One foot = 12 inches
Half a foot = 6 inches
Now, we add up all the sides to find the total perimeter in inches.
3 + 3 + 3 + 3 + 3 + 3 + 6 + 6 + 6 + 6 = 42 inches
The total perimeter is 42 inches.
