Answer 1

Step-by-step explanation:

join BD,Cutting ef at m

now in triangle Bad,E is the mid point of Ba and em parallel to ad (1)

..Em =1/2 AD

AGAIN IN TRIANGLE BCD, F IS THE MID POINT OF CD AND MF PARALLEL TO BC (2)

MF = 1/2 BC

EF=EM+ MF

EF=1/2×AD+1/2×BC

EF=1/2 (AD+BC)

EF=1/2 (80+50)

EF=1/2×130

EF=65
