Question

figure b is a scaled copy of figure a.
what is the scale factor from figure a to figure b?
figure a (a green trapezoid with side lengths 4, 4, 4.4, 6)
figure b (a blue trapezoid with side lengths 1, 1, 1.1, 1.5)

Explanation:

Step1: Identify corresponding sides

Find a pair of corresponding sides from Figure A and Figure B. For example, a side of length 4 in Figure A corresponds to a side of length 1 in Figure B.

Step2: Calculate scale factor

The scale factor from Figure A to Figure B is the length of the side in Figure B divided by the length of the corresponding side in Figure A. So, scale factor $= \frac{1}{4} = 0.25$ (or we can check other sides: $\frac{1.1}{4.4} = 0.25$, $\frac{1.5}{6} = 0.25$ to confirm).

Answer:

0.25
