Never heard about permeter of triangle you must have read or typed it wrong it must be perimeter of lf triangle. All legitimate 12 th standard students know the general formula for it. But if you are asking about special case then its just the application of general case.

For example you have given all three sides of triangle
AB = 6 BC =10 and Ac = 5 find the perimeter of triangle
Solution
Perimeter of triangle= sum of all sides
=AB+BC+AC
=6+10+5
=21

Why we cant divide anything with 0

Posted by Tiyas Chakraborty 7 years, 7 months ago

CBSE > Class 12 > Mathematics

Rishabh Sahu 7 years, 7 months ago

Try yourself to find the answer on division by 0 using properties of multiplication and division. 1*0=0,2*0=0. If then you define from 1=0/0 ,2=0/0 then say 1=2 or 0=1/0and 0=2/0 respectively from the equations and then you will equate 1=2 then all the other study properties and definition of numbers is senseless. No one has given a value to 1/0 ,if one tries to define such a value by euclids division lemma then there is no unique quotient if divisor is 0. Therefore we say division by 0 is not defined because it doesn't make sense.
