As shown in the figure, given that BC = 1 / 3AB = 1 / 4CD, points E and F are the midpoint of AB and CD respectively, and EF = 60cm, calculate the length of AB and CD As shown in Figure a________ E__ C________ B___________ D

As shown in the figure, given that BC = 1 / 3AB = 1 / 4CD, points E and F are the midpoint of AB and CD respectively, and EF = 60cm, calculate the length of AB and CD As shown in Figure a________ E__ C________ B___________ D

BC=1/3AB=1/4CD
AB=3BC,CD=4BC
E. F is the midpoint of AB and CD
EB=1/2AB=3/2BC,CF=1/2CD=2BC
EF=EB+CF-BC=3/2BC+2BC-BC=5/2BC=60
BC=24
AB=3BC=72,CD=4BC=96
