Question

1 figure b is a scale - drawing of figure a. estimate the scale factor that relates figure b to figure a. explain your estimate.

Explanation:

Step1: Select a measurement

Choose a length on figure A, like the length of the thumb. Measure it (let's assume it's 2 cm).

Step2: Measure the corresponding length on figure B

Measure the length of the thumb on figure B (let's assume it's 4 cm).

Step3: Calculate the scale - factor

The scale factor is the ratio of the length in figure B to the length in figure A. So, scale factor=$\frac{\text{Length in figure B}}{\text{Length in figure A}}=\frac{4}{2} = 2$.

Answer:

The scale factor is 2. This means that figure B is twice as large as figure A in terms of linear dimensions, as when we compared a corresponding length (the thumb length in this case) between the two figures, the length in figure B was double the length in figure A.
