Solution:
______________________________

$area \: of \: the \: plot = 200 \times 150 = 30000 {m}^{2}$

$area \: of \: roads = 3 \times (200 \times 3) = 1800 {m}^{2}$

$area \: avialable(left) \: for \: building \: the \: houses \: = area \: of \: the \: plot - area \: of \: the \: roads \:$

$30000 - 1800 = 28200 {m}^{2}$

$therefore \\ \\ area \: available \: for \: building \: the \: houses = 28200 {m}^{2}$
