Answer:

The perimeter before is 5+4+5+4=18.

After doubling the length, we do 10+4+10+4=28.

The difference is 10, so the perimeter increases by 10.

The change in perimeter should be 10.

Calculation of the perimeter:

Before doubling the length, the perimeter is

= 5 + 4 + 5 + 4

= 18

Since the length is doubles, so here the perimeter should be

= 10+4+10+4

=28

Now the difference should be

= 28 - 18

= 10

Therefore, we can conclude that The change in perimeter should be 10.
