You can put this solution on YOUR website!
Perimeter of a triangle is 2x(length+breadth)
\n" ); document.write( "You are given that one side = 14 and the other side = a
\n" ); document.write( "Also perimeter = 38
\n" ); document.write( "So we get 2x(14+a) = 38
\n" ); document.write( "Dividing both sides by 2
\n" ); document.write( "14+a = 19
\n" ); document.write( "Subtracting 14 from both sides
\n" ); document.write( "a = 5cms
\n" ); document.write( "
\n" );
