The plot of the polygon is attached and the perimeter is 24.1 units
How to find the perimeter
Perimeter of a polygon is the sum of the sides.
From the plot the distances between the sides are
AB = 7.3 units
BC = 6 units
CD = 3.6 units
DA = 7.2 units
Perimeter = AB + BC + CD + DA
= 7.3 + 6 + 3.6 + 7.2
= 24.1 units
