DP=MP-MD=9-7=2 cm
MC=6 cm
CD=MD-MC=7-6=1 cm
CP=CD+DP=1+2=3 cm
MB=4 cm
BC=MC-MB=6-4=2 cm
MA=2 cm
AB=MB-MA=4-2=2 cm
NA=2.5 cm
OC=3 cm
QD=2 cm
RB=2.5 cm
AC=AB+BC=2+2=4 cm
BD=BC+CD=2+1=3 cm
Area of triangle=1/2xbxh
Area of trapezium=1/2(sum of parallel sides)xheight
Area of Polygon MNOPQR=ar(MAN)+ar of trapezium(ACON)+ar(OCP)+ar(MBR)+ar of trapezium(BRQD)+ar(QDP)
Area of Polygon MNOPQR=
1/2(2)(2.5)+1/2(2.5+3)(4)+1/2(3)(3)+1/2(4)(2.5)+1/2(2.5+2)(3)+1/2(2)(2)
Area of Polygon MNOPQR=2.5+11+4.5+5+6.75+2=31.75 square cm
