1) The length of the side of a triangle are
a )   4 x 2 - 3 x + 7 b )   - x 2 + 2 x - 9 c )   5 x 2 - 4 x + 8
Find its perimeter.

Please find below the solution to the asked query:

Length of sides of triangle  =  4x2 - 3 x + 7 ,  - x2 + 2 x - 9 and  5 x2 - 4 x + 8 , So

Perimeter of triangle  = ( 4x2 - 3 x + 7 ) + (  - x2 + 2 x - 9 ) + ( 5 x2 - 4 x + 8 ) = 4x2 - 3 x + 7   - x2 + 2 x - 9 + 5 x2 - 4 x + 8 = 8 x2 - 5 x + 6                           ( Ans )
