Step-by-step explanation:

$to \: find : \\ 1.values \: of \: a \\ 2.coordinates \: of \: \: 4 \: vertices \\ \\ so \: here \: line \: segment \: joining \: \\ points \: AS \: is \: divided \: into \\ four \: congruent \: parts \: namely \\ P \:and \: Q \:and \: R$

$so \: hence \: then \\ Q \: is \: midpoint \: of \: AS \\ \\ thus \: then \\ Q = (x ,y) = (12 ,a + 4) \\ A= (x1 ,y1) = (2a ,a) \\ S= (x2 ,y2) = (a - 6 ,2a - 2) \\ \\ so \: by \: midpoint \: formula \\ we \: get \\ \\ x = \frac{x1 + x2}{2} \\ \\ 12 = \frac{2a + a - 6}{2} \\ \\ 24 = 3a - 6 \\ \\ 24 = 3(a - 2) \\ \\ 8 = a - 2 \\ \\ a = 10$

$hence \: then \\ A = (20,10) \\ S = (4,18) \\ Q= (12,14)$

$again \: then \: here \: \\ P \: and \: R \: are \: midpoints \: of \: \\ AQ \: and \: QS \: respectively \: \\ \\ again \: apply \: midpoint \: formula \: \: \\ and \: find \: its \: \: coordinates$
