Final answer:
In the context provided, 1.75 meters (actual length of the model plane) equates to 175 centimeters. Therefore, since a meter is the standard unit, we can deduce that 1 meter is equivalent to 100 centimeters which is the correct answer to the question.
Step-by-step explanation:
The question asks us to determine how many centimeters equal 1 meter using the information that in a scale drawing, a model plane has a length of 35 centimeters and its actual length is 1.75 meters. To solve this, we can set up a ratio using the scale model's length and the actual length.
Since 1.75 meters is the same as 175 centimeters (because 1 meter equals 100 centimeters), we can write this ratio as 35 cm (model plane) : 175 cm (actual plane). To find out how many centimeters equal 1 meter, we look for the ratio of 1 meter to its equivalent in centimeters.
I can tell you that the answer to the question is A) 100 cm.
