Final answer:
To draw the bridge to scale, use the scale factor of 1/200 and multiply the actual length of the bridge by this factor to get the length in the drawing.
Step-by-step explanation:
To draw the bridge to scale, first, determine the scale factor. The scale factor is the ratio of the drawing's size to the actual size of the bridge. In this case, the scale factor is 1/200.
To find the length of the bridge in the drawing, multiply the actual length by the scale factor. So, 3910 meters x 1/200 = 19.55 centimeters.
Therefore, to draw the bridge to scale, you would draw it as a line segment with a length of 19.55 centimeters.
