Question

The scale drawing below shows an enlargement by a scale factor of 2.

Answer 1

Answer:

4.5

Step-by-step explanation:

The scale factor is 2

This means that the sides are proportional by a factor of 2.

In other words, you multiply 2 with the side lengths of first trapezoid to get the side length of second trapezoid.

You can see the pattern:

12 goes with 24

4.5 goes with 9

7 goes with 14

X goes with 9

The "X" is the missing side.

As you can see, we multiply each number on the left-hand side by 2 to get the number on the right-hand side (larger trapezoid).

So, that means:

X multiplied by "2" will gives us 9, we can write:

$x*2=9$

Complete the equation and find x:

$x*2=9\\2x=9\\x=\frac{9}{2}\\x=4.5$

The missing side length in the original trapezoid is "4.5"
