Question

Two sides of a triangle are 0.5 cm and 3 cm. Which of the following can be the measure of third side
(A) 1 (B) 2 (C) 3 (D) 4

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

Answer:

3

Step-by-step explanation:

sum of 2 sides of a triangle has to be greater than third side and difference of the two sides has to be less than the third side .

so ,

0.5+3 = 3.5

3-0.5 = 2.5

thus , only one option fits in this situation and that is 3
