There is no question here. However, it must be a lot of work to tend a garden 15 meters HIGH. I assume it is a vertical garden, but 15 meters is a long way to climb to tend the top row.
No, the 20x15 lot costs 300*8 = 2400

So, the larger lot costs 2400*2*2 = 9600
Yes; if the dimensions are doubled, the area is multiplied by 1/4.
