Answer:
15 feets
Step-by-step explanation:
Perimeter of a rectangle = 2(l + w)
l = Length ; w = width
Perimeter, p = 48
Length of all sides
p = 2(l + w)
48 = 2(l + 9)
48 = 2l + 18
48 - 18 = 2l
30 = 2l
l = 30/2
l = 15
Length of the sides = 15 feets
3x-6≤9
3x≤15
x≤5
so the answer is x≤5
5-2=3 so therefore y=3
Remember to work backwards and use opposite operations.
