Question

The lengths of the three sides of the triangle are 4cm, 5cm and 7cm respectively. Which of
the following cannot be the length of any one of the medians?
(A) 2.5 cm
(B) 5 cm
(C) 3.8 cm
(D) none of these
​

Answer 1

Answer:

(I) We know that (3+4) cm is greater than third side.

Thus, the third side is smaller than 7 cm

(ii) we know that (4−3) cm is smaller than third side .

Thus, the third side is greater than 1cm.

Therefore, 1 cm < third side <7 cm.

Thus, 5 cm can be the length of third side for a triangle.

Answer 2

B) 5 cm.

5 cm can be the length of third side.
