Answer:
6x + 2 and 2x + (x + 1) + 2x + (x + 1)
Step-by-step explanation:
Perimeter of a rectangle = 2(length + width)
Length = 2x
Width = x + 1
Perimeter of a rectangle = 2(length + width)
= 2{2x + (x + 1)}
= 2(2x + x + 1)
= 2(3x + 1)
= 6x + 2
Perimeter = length + width + length + width
= 2x + (x + 1) + 2x + (x + 1)
