A square had sides of length s. A rectangle is 6 inches shorter than the square and 1 inch longer . Which of the following represents the perimeter?

Answer: D
Step-by-step explanation:
(1st) A is given as a=s
2nd ) b=s+1
3rd) the perimeter will be written as : both sides + both widths
so 2(s+1) + 2(s-6)
expand it so it becomes 2 s + 2 +2 s -12
4th combine like terms = 4 s -10
