50m is the total length of the paths, but that was not the question.
30m*20m = 600m^2
you don't say which path runs the length and which the width. If the wider path is the longer, then the area used up by the paths is
.8*30 + .7*20 - .8*.7 = 37.44
So, that leaves 600-37.44 = 562.56 m^2 for the garden.
If the wider path is the shorter one, then change the numbers accordingly.
