Asap answer quadrilateral abcd is dilated at center (0,0) with scale factor 1/2 to form quadrilateral a'b'c'd'. wha is the length of a'b'?

a. sqrt5

b.2

c.10

d.2sqrt5

The quadrilateral ABCD is dilated at the center (0,0) with a scale factor of 1/2. So, after the dilation the length of A'B' is and this can be determined by using the formula of length between two points.

Given :

Given that the quadrilateral ABCD is dilated at the center (0,0) with a scale factor of 1/2. So the points of the quadrilateral ABCD becomes:

Now, the length of A'B' is given by:

Therefore, the correct option is a).

Step-by-step explanation:

The points A and B have coordinates at (0,4) and (4,2) respectively.

The distance formula can be used to find the length of AB.

Since quadrilateral ABCD was enlarged with  a scale factor of .

The length of A'B' is

12
