Question

the perimeter of a triangle is 15whole 1/5 m and other two side are 5 whole 1/3 and 3whole 1/3 ,then what is length of third side
​

Answer 1

Answer:

Correct option is

C

6 cm

⇒ The sum of the lengths of any two sides in a triangle is always greater than the length of the third side in the triangle.

⇒ The differnce of the lengths of any two sides in a triangle is always lesser than the length of the third side in the triangle.

⇒ The difference between 4cm and 7cm is

3cm and their sum is 11cm.

⇒ To ensure that the above mentioned rule is not violated, the possible length of the third side has got to be greater than 3cm and lesser than 11cm.

⇒ So from the given options 6cm is less than

11cm and greater than 3cm

∴ The length of the third side of triangle is 6cm
