Answer:
hello :
the perimeter is : p = 2(w +l)
w :width.... l : the length
54 = 2(w + 23.5)
w+23.5 = 27
w =23.5 ft
The two triangles with the given perimeter is attached .
Perimeter is the sum of all sides.
For the first triangle , sies are 2a,2a and b.
So the perimeter is

For the second triangle, sides are a,a, and 2a+b. Therefore perimeter is

So for both triangles, perimeter is

Circumference= 15.71 feet squared
