If `A, B, C, D and E` are five coplanar points, then the value of `bar(DA)+bar(DB)+bar(DC) + bar(AE) +bar( BE) +bar (CE)` is equal to

A

DE

B

3DE

C

2DE

D

4ED

Text Solution

Verified by Experts

The correct Answer is:
B
A,B,C,D and E are five coplanar points.
`DA+DB+AE+BE+CE`
`=(DA+AE)+(DB+BE)+(DC+CE)`
`=DE+DE+DE=3DE`
