Answer:

The perimeter of the rectangle is equal to $(10x-30)\ cm$

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

$P=2(L+W)$

we have

$L=(3x-8)\ cm\\W=(2x-7)\ cm$

substitute

$P=2((3x-8)+(2x-7))$

$P=2(5x-15)$

$P=(10x-30)\ cm$
