6 units

7.6 units

9.5 units

12 units

Answer 1

The answer is 6

Explanation

Took edge

Answer 2

The first thing we must do for this case is to calculate the scale factor.

For this, we make the relationship between two parallel sides.

We have then:

`image`

Substituting values we have:

`image`

We are now looking for the value of AB

We have then:

`image`

Substituting values:

`image`

Answer:

The scale factor is:

`image`

The value of AB is:

`AB = 6`
