Answer:
172.5 cm
Step-by-step explanation:
The scale of the model is 1 : 200, therefore the length of 1 m in the model represent the actual length of 200 m
200 m actual length = 1 m model length
1 m actual length = 1 ÷ 200 = 0.005 m model length
1 m actual length = 0.005 m model length
345 m actual length = 345 x 0.005 m = 1.725m model length
The answer wants it in cm, so we convert the m to cm.
1.725m = 172.5 cm
