Question

6. If two sides of a triangle are 3 cm
and 4 cm then the length of third
side should be​

Answer 1

Answer:

Third side of triangle = 5cm.

Step-by-step explanation:

First side = 3cm.

second side = 4cm.

other side = h^2=p^2+b^2

h^2 = 3^2 + 4^2

h = √9+16

h =√25

h= 5cm..

hope it's useful mark me as brainliest and give thank also......

Answer 2

5 cm 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.
