If D and E are respectively the midpoints of the sides AB and BC of `triangle ABC ` in which AB = 7.2 cm, BC = 9.8 cm and AC = 3.6 cm then determine the length of DE.

D and E are respectively the points on the sides AB and AC of a triangle ABC such that AE = 5 cm, AC= 7.5 cm, DE= 4.2 cm and DEabs() BC . Then find length of BC.

D and E are respectively the points on the sides AB and AC of a triangle ABC such that AD = 2 cm , BD = 3 cm , BC = 7.5 cm and DE || BC. Then length of DE (in cm) is (a) 2.5 (b) 3 (c) 5 (d) 6

D and E are respectively the points on the sides AB and AC of a triangle ABC such that AD = 2cm, BD = 3 cm, BC = 7.5 cm and DE |\ | BC. Then, length of DE (in cm) is (a) 2.5 (b) 3 (c) 5 (d) 6

In triangle ABC, given below, AB = 8 cm, BC = 6 cm and AC = 3 cm. Calculate the length of OC

D and E are respectively the points on the side AB and AC of a bigoplus ABC such that AB=5.6cm,AD=1.4cm,AC=7.2cm and AE=1.8cm, show that DE|BC .

In the figure, D, E are the midpoints of the sides AB and AC. If DE=4 cm,then BC=

In triangle ABC , AB = 6 cm, AC = 8 cm, and BC = 9 cm. The length of median AD is:

In a right-angled triangle ABC, if angle B = 90° , BC = 3 cm and AC = 5 cm, then the length of side AB is
