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

Step-by-step explanation:
Answer:
144
Step-by-step explanation:
(2*6)*(3*4)=12*12=144
The perimeter is all sides length added together. You can make an equation:5+5+x+x where x is the length.
5+5=10 18-10=8 There is two sides so you do eight divided by two
The length is 4
First, since the building is 5.5 inches and the scale is 1 inch for 8 feet, you would multiply 5.5* 8 to get 44 feet.
