cool. lets start from the start. Picture , good we are solving a system of 3 equations, two are the equation for the area, an one is the relationship between the two areas. From the diagram we can see that 1. the area of the garden is the area of the rectangle ={width} x {length} \[A_G=20ft \times 12ft\]\[=120ft^2\] 2. the area of the walkway is the area of the rectangle minus the area of the garden \[A_W = (2x+20)ft \times (12+3)ft A_G\]\[ = 2(x+10)ft\times 15ft120ft^2\] 3. the question states that the area of the walkway is half the area of the garden\[A_W=\frac{1}{2}A_G\] \[SSubsitute 1. and 2. into 3. and solve
