I would start at making it more easy by asking my dad or mom for help
the picture in the attached figure
Step 1
Find the perimeter of the scaled-down model of a walkway (Quadrilateral ABCD)

Step 2
Find the scale factor
if Quadrilateral ABCD is similar to Quadrilateral EFGH
then


Step 3
Find the perimeter of the actual walkway (Quadrilateral EFGH)



therefore
the answer is

2 and 2/3
This will be tha answer I tjink
Answer:
216°
Step-by-step explanation:
The ratio of the sum of smallest and largest to the total of all angles is ...
(9 +15)/(9 +10 +12 +14 +15) = 24/60 = 0.4
__
The total of all angles in an n-gon is 180°(n -2), so the total of all angles in a pentagon is ...
180°(5 -2) = 540°
Then the sum of smallest and largest angles is ...
0.4(540°) = 216°
