Question

PLEASE HELP !! Figure B is a scaled copy of Figure A. What is the scale factor from Figure A to Figure B?

Answer 1

Answer:

The scale factor from Figure A to Figure B is $0.5$

Step-by-step explanation:

we know that

If two figures are similar, then the ratio of its corresponding sides is the scale factor

Let

z-----> the scale factor

In this problem

$z=\frac{hB}{hA}$

substitute values

$z=\frac{2}{4}=0.5$

the scale factor is less than 1

therefore

is a reduction

Answer 2

Answer: $\dfrac{1}{2}$

Step-by-step explanation:

Given : Figure B is a scaled copy of Figure A.

• We know that the scale factor is the ratio of the corresponding sides of two similar figures.

From , the graph we assume that that one point = one unit of length.

Then, the dimension of one side of figure A = 4 units and the  dimension of  corresponding side of Figure B = 2.

Then, the scale factor is given by :-

$k=\dfrac{2}{4}=\dfrac{1}{2}$

Hence, the  scale factor is $\dfrac{1}{2}$
