Answer:

[tex]l=155cm[/tex]

Step-by-step explanation:

Given the following question:

[tex]P=2(l+w)[/tex]
[tex]P=400cm[/tex]
[tex]w=45cm[/tex]

In order to find the length of the given rectangle complete the following steps.
[tex]400\div2=200[/tex]
[tex]200-45=155[/tex]
[tex]l=155cm[/tex]

Check your work:
[tex]P=2(l+w)[/tex]
[tex]l=155[/tex]
[tex]w=45[/tex]
[tex]P=2(155+45)[/tex]
[tex]155+45=200[/tex]
[tex]2\times200[/tex]
[tex]2\times200=400[/tex]
[tex]p=400cm[/tex]
