Paolo wrote the following equation for the perimeter of a rectangle.

p=2(l+w)

a. w=p-21
b. w=p-1
c. w=p-21/2
d. w=p+21/2

The answer is the option C

Step-by-step explanation:

we know that

The perimeter of a rectangle is equal to

where

L ---->  is the length side of rectangle

W ----> is the width side of the rectangle

Solve for W

That means -------> isolate the variable W

Divide by both sides

Subtract both sides

y/x=18
