Asquare has sides of length s. a rectangle is 6 inches shorter than the square and 1 inch longer. which of the following expressions represents the perimeter of the rectangle?

a. s^2 - 5s+6

b. s^2 - 5s-6

c. 2s - 5

d. 4s - 10

D. 4s - 10

Step-by-step explanation:

Given: A square has sides of length 's'.

A rectangle is 6 inches shorter than the square and 1 inch longer.

Thus rectangle has breadth = s-6

and length=s+1

Then the perimeter of the rectangle= 2(length+breadth)

⇒Perimeter of the rectangle=2(s+1+s-6)

Perimeter of the rectangle=2(s+s+1-6)

Perimeter of the rectangle=2(2s-5)

Perimeter of the rectangle=4s-10.
