Answer:
96 ft
Step-by-step explanation:
You want the perimeter of pentagon JKLMN, given it is congruent to pentagon ABCDE with side lengths marked.
Congruence
The fact that the figures are congruent means corresponding sides have the same length. That is, KL = 12 ft, LM = 32 ft, MN = 12 ft. The hash marks on JN and JK mean those are the same length.
Perimeter
The perimeter of the figure is the sum of its side lengths:
Perimeter = JK +KL +LM +MN +NJ
= 20 ft +12 ft + 32 ft +12 ft +20 ft = 96 ft
The perimeter of figure JKLMN is 96 ft.
