Let the width of the rectangle be 'w'
According to the question length of the rectangle (l) is three feet more than twice it's width;
l = (2w + 3) ft
Perimeter of rectangle = 78 ft
Formula of perimeter of rectangle = 2(Length + Width)
So,

Width of the rectangle (w) = 12 ft
Answer:
It's exponential growth.
Step-by-step explanation:
