Answer 2

The length of EF is 7 cm.

Given:

BC=14 cm

To find:

The length of EF

Solution:

We can obtain the length by using the concept of the line joining the midpoints.

We know that EF is formed by joining the midpoints E and F.

So, it will be parallel and half of the side BC.

The length of EF=BC×1/2

Using the values,

EF=1/2×14

EF=14/2

EF=7 cm

Therefore, the length of EF is 7 cm.
