Given that the line segment ad = 6cm, the line segment AC = BD = 4cm, the points E and F are the midpoint of the line segments AB and CD respectively, the length of the line segment EF is calculated Please, class is coming!

Send you the answers I found
Because AC = BD = 4, so AC + BD = 8
Because AC + BD = AB + BC + BC + CD = AD + BC = 8
Because ad = 6, so 6 + BC = 8, so BC = 2
So AB = ac-bc = 4-2 = 2, CD = bd-bc-4-2 = 2
Because e and F are the midpoint of line AB and CD respectively
So be = 1 / 2Ab = 1 CF = 1 / 2CD = 1
So EF = EB + BC + CF = 1 + 2 + 1 = 4C
