Question

if sides of a triangle is 2a,2band 2c . what is the semi perimeter of a triangle​

Answer 1

Answer:

a+b+c

Step-by-step explanation:

Given ,

The 3 sides of Triangle are 2a,2b and 2c respectively.

Therefore, The semi perimeter of the given triangle

= perimeter of triangle/ 2

The perimeter of triangle = sum of the space sides of the triangle

= 2a+2b+2c

Therefore semiperimeter of triangle =2a+2b+2c/2

= 2(a+b+c)/2

= a+b+c
