Answer :
The scale factor of the drawing is 1cm : 0.29m.
What is the scale factor?
A scale drawing is a smaller image of a larger image or object. The scale drawing is usually reduced at a constant dimension.
The scale factor is the ratio of the dimension of the scale drawing to the original object. The scale factor is the measurement used to convert the larger image into a smaller version of the original object. The scale factor is usually written in this format - 1, a colon (:), then the matching length on the original image. e.g. 1 : 10
Scale factor of the drawing = original dimensions / dimensions of the scale drawing
2 / 7 = 0.29
