Question

explain step by step solution​

Answer 1

Step-by-step explanation:

area of the triangle ABP = (1/2)*BP*AR

=(1/2)*(BR+RP)*AR

= (1/2)*(60+40)*50

=(1/2)*100*50

=50*50

=2500

and the area of the triangle DQC=(1/2)*DQ*QC

=1/2 *BP*QC= (1/2)*(100)*(70)

=50*70= 3500

NOW the area of the triangle QBC

= (1/2)*QC*BR

=(1/2)*70*60

= 2100

so area of the parallelogram =

15600-2100-3500-2500

=7500 cm^2
