Step-by-step explanation:
Let the width of the garden be b and its length is 9 feet less than 3 times the width.
Length = 3b-9 ...(1)
The perimeter of the garden = 63
We need to find the system of equations that represents is the dimensions of the rectangular garden.
Perimeter = 2(l+b)
63 = 2(3b-9+b) [from equation (1)]
31.5 = (3b-9+b)
31.5 = (4b-9)
31.5+9 = 4b(2)
b = 10.12
Hence, the equations are showsn in equation (1) and (2).
