Question

In the adjacent figure, N and M are midpoints of AC and BD respectively. BC = 8 units and AD = 6 units. Find length (MN) 1) 3 2) 3.5 3) 5 4) 5.25

Answer 1

Thus the length of Mn = 3 units

Option (3) is correct.

Step-by-step explanation:

We are given that:

N and M are midpoints.

BC = 8 units

AD = 6 units

To Find: Length (MN) = ?

MN =  1/2 BD

MN =  1/2 (6)

MN =  3 units

Thus the length of MN = 3 units

Answer 2

Step-by-step explanation:

Draw a perpendicular from N

soo we are getting a similarity of triangles

by that we get NE(E= Perpendicular drawn from N to BC)

NE=3

ME=4

Therefore we get MN=5
