Answer:

5.0n+7.0

Step-by-step explanation:

Perimeter of a rectangle = 2(L+W)

L is the length = 5n-2.5

W is the width = 2.5n+6

Perimeter of the rectangle = 2(5n-2.5+2.5n+6)

Perimeter of the rectangle = 2(2.5n+3.5)

Perimeter of the rectangle = 5.0n+7.0

Hence the perimeter of the rectangle is 5.0n+7.0
