Four sides of trapezoid

Trapezoid is given by length of four sides: 40.5 42.5 52.8 35.0. Calculate its area.

Correct answer:

S =  1414.5937

Step-by-step explanation:

a=40.5 b=42.5 c=52.8 d=35.0  x=ca=52.840.5=10123=12103=12.3 s=(b+d+x)/2=(42.5+35+12.3)/2=10449=44109=44.9 S1=s (sb) (sd) (sx)=44.9 (44.942.5) (44.935) (44.912.3)186.4898 h=2 S1/x=2 186.4898/12.330.3236 S2=a h=40.5 30.32361228.1039 S=S1+S2=186.4898+1228.1039=1414.5937
