Answer:
The perimeter of the rectangle is equal to [tex](10x-30)\ cm[/tex]
Step-by-step explanation:
Let
L-----> the length of the rectangle
W ----> the width of the rectangle
we know that
The perimeter of rectangle is equal to
[tex]P=2(L+W)[/tex]
we have
[tex]L=(3x-8)\ cm\\W=(2x-7)\ cm[/tex]
substitute
[tex]P=2((3x-8)+(2x-7))[/tex]
[tex]P=2(5x-15)[/tex]
[tex]P=(10x-30)\ cm[/tex]
