In ΔDEF, M and N are the points on sides DE and DF respectively. MN is parallel to EF and MN : EF = 2: 5. If DE = 60 cm, then what is the length of ME ?
Answer & explanation
Correct answer: option 4
We know that the ratio of MN to EF is equal to the ratio of DM to DE and also equal to the ratio of DN to DN
So DE = EF = 60
ME = 5x - 2x = 3x
5x = 60
x = 12
3x = ME = 36
