One trapezium

One trapezium has AB=24M, BC=36M, CD=80M, DA=80M long sides. Find the area.

Correct answer:

A =  1633.8636 m2

Step-by-step explanation:

a=24 m b=36 m c=80 m d=80 m  x=ca=8024=56 m  s=x+b+d2=56+36+802=86 m  S1=s (sx) (sb) (sd)=86 (8656) (8636) (8680)=60 215 m2879.7727 m2  S1=xh/2  h=2 S1/x=2 879.7727/5631.4205 m  A=a+c2 h=24+802 31.4205=1633.8636 m2
