Answer: P = 25n + 35
Step-by-step explanation:
The perimeter of a rectangle is twice the sum of length and width.
P = 2(l +w)
P = 2((8.5n+9) + (4n +8.5))
P = 2(12.5n +17.5)
P = 25n + 35
Obtuse angles are more than 90° and less than 180°
180 times 4/100= 7.20- Sales tax
180+7.20= $187.20 is the total cost
