Question

what is the unknown value in the scale? 5 m explain your thinking.

Explanation:

Step1: Observe scale - length relationship

The larger image has a scale of 10 m. Assume the two images are similar and the scale changes proportionally. If we assume the smaller image is half the size of the larger one in terms of the scale - related dimension.

Step2: Calculate the unknown scale

Since the relationship seems to be a factor of 2 (by visual comparison of the overall size of the two images), if the larger scale is 10 m, then the unknown scale is $\frac{10}{2}=5$ m.
