Answer:
17n+9 feet
Step-by-step explanation:
The perimeter of a rectangle is twice the sum of length and width.
P = 2(L +W)
P = 2((4.5n +9) +(4n -4.5)) = 2(8.5n +4.5)
P = 17n +9
The perimeter of the rectangle is 17n +9 feet.
Answer:
The equation of the perpendicular line is 2 x + y + 1 =0
Step-by-step explanation:
<u><em>Step(i) </em></u>:-
Given equation of the line 2y = x - 18
x - 2y - 18 =0
The equation of the perpendicular line to the given line
b x - ay +k=0
-2 x - y + k =0 this line is passing through the point ( 0 , -1)
⇒ 0 -(-1) + k=0
⇒ 1+k =0
⇒ k = -1
<u><em>Step(ii):-</em></u>
The equation of the line is perpendicular to the line
-2x - y - 1 =0
2 x + y + 1 =0
<u><em>Conclusion:-</em></u>
The equation of the perpendicular line to the given line 2 x + y + 1 =0
