Answer:
100cm
Step-by-step explanation:
From the given diagram;
Perimeter of the polygon = AB + BC+ CD + DA
Perimeter of the polygon = 11.5 + 12.5 + 12.5 + 13.5 + 13.5 + 12.5 + 12.5 + 11.5
Perimeter of the polygon = 24 + 26 + 26 + 24
Perimeter of the polygon = 50 + 50
Perimeter of the polygon = 100cm
Hence the Perimeter of the polygon is 100cm
