the area of parallelogram=bh
bredth (b) =9m
height(h)=30.8m
area of parallelogram =9(30.8)
=>277.2m^2
area of triangle=(bh)/2
BE=(breadth)
BE^2=BC^2-CE^2
BE^2=(30.8)^2-25^2
BE^2=323.65
BE=17.9
area of triangle=[17.9(25)]/2
=>223.75
the area = area of paralleogram +area of triangle
=>277.2+223.75=500.9
paralleogram perimeter=2(a+b)
=2(9+30.8)=2(39.8)
=>79.6
