Trapezoid - central median

The central median divides the trapezoid into two smaller trapezoids. Determines the ratio of their contents.

Result

p = (Correct answer is: (3a+c)/(a+3c)) Wrong answer

Solution:

S1=((a+c)/2+c)h/2 S2=((a+c)/2+a)h/2 p=S2:S1=((a+c)/2+a)/((a+c)/2+c) p=(1.5a+0.5c)/(0.5a+1.5c) p=(3a+c)/(a+3c)S_{1}=((a+c)/2+c)h/2 \ \\ S_{2}=((a+c)/2+a)h/2 \ \\ p=S_{2}:S_{1}=((a+c)/2+a)/ ((a+c)/2+c) \ \\ p=(1.5a+0.5c)/(0.5a+1.5c) \ \\ p=(3a+c)/(a+3c)
