# How do you find the perimeter of a rectangle with length 3c-5 and width 2c?

$p = 10 c - 10$

#### Explanation:

The equation for the perimeter of a rectangle is $p = 2 L \cdot 2 W$ where $p 3 i s t h e p e r i m e t e r ,$L$i s t h e \le n > h o f t h e r e c \tan g \le \mathmr{and}$W# is the width of the rectangle. Substituting what is known:

$p = 2 \left(3 c - 5\right) + 2 \left(2 c\right)$

Then simplify:

$p = 6 c - 10 + 4 c$

$p = 10 c - 10$
