The expression for the perimeter of rectangle with length L & breadth B is :
Perimeter of Rectangle = 2(Length + Breadth)
From the given figure:
Length = 9x + 3
Breadth = x - 5
Perimeter of rectangle = 2 ( 9x + 3 + x - 5)
Perimeter of rectangle = 2 ( 10x -2 )
Perimeter of rectangle = 20x - 4
Answer : B) 20x - 4
