Answer:
The perimeter of the figure is [tex]90\ ft[/tex]
Step-by-step explanation:
Let
[tex]A(1,5),B(6,5),C(6,1),D(1,1)[/tex]
using a graphing tool
see the attached figure
The perimeter is equal to
[tex]P=AB+BC+CD+AD[/tex]
The figure is a rectangle
so
[tex]AB=DC=(6-1)=5*5=25\ ft[/tex]
[tex]AD=BC=(5-1)=4*5=20\ ft[/tex]
[tex]P=2(25+20)=90\ ft[/tex]
