The width of a rectangle is 5n - 3.5 feet and the length is 3.5n + 9 feet. Find the perimeter of the rectangle.
juin [17]

Answer:

17n+11

Step-by-step explanation:

Formula For Perimeter Of Rectangle: 2(Length) + 2(Width)

                                                            Length = 3.5n + 9

                                                            Width =  5n - 3.5

____________________________________________________

-> 2(Length) + 2(Width)

-> 2(3.5n+9) + 2(5n-3.5)

*distribute*

-> (7n+18) + (10n-7)

*distribute*

->7n+18+10n-7

->17n-11
