The width of rectangle is 3 units.
Step-by-step explanation:
Given,
Area of rectangle = Perimeter of rectangle
Let,
width of rectangle = w
Length of rectangle = w+3
Area = Length*Width
Perimeter = 2(Length+Width)
It is given that;
Area of rectangle = Perimeter of rectangle

Factorizing the equation,

Either,
w-3=0 => w=3
Or,
w+2=0 => w= -2
As width cannot be negative, therefore,
The width of rectangle is 3 units.
