Answer:

a) 3/4

b) 21/4

Explanation:

To find the scale factor from A to B take any side of B and divide it by the corresponding side of A

The ratio will be the same for all sides

We have
scale factor = 3/4

We see that the sides 9 and 12 are also in this ratio: 9/12 = 3/4

a) So scale factor from A to B is 3/4

b) w of shape B corresponds to the side with length 7 in shape A

The ratio of w to 7 must be equal to the scale factor

So w/7 = 3/4

w = 7 x 3/4

w = 21/4
