Question

enlargement k =

1. enlargement k =

Explanation:

Step1: Determine side - length ratio for first pair

Measure corresponding side - lengths of figures A and B in the first grid. Suppose a side of figure A is 1 unit and the corresponding side of figure B is 5 units. The ratio of the side - length of B to A gives the scale factor of enlargement.

Step2: Determine side - length ratio for second pair

In the second grid, measure corresponding side - lengths of figures A and B. If a side of figure A is 1 unit and the corresponding side of figure B is 2 units, the scale factor of enlargement is the ratio of these side - lengths.

Answer:

For the first problem: 5
For the second problem: 2
