The side of a triangle is twice the length of the shortest side and
\n" ); document.write( "a = 2c
\n" ); document.write( " the middle length side is 9 inches longer than the shortest side.
\n" ); document.write( "b = c + 9
\n" ); document.write( " If the perimeter is 65 inches what are the lengths of the 3 sides?
\n" ); document.write( "a + b + c = 65
\n" ); document.write( "Replace a and b
\n" ); document.write( "2c + (c+9) + c = 65
\n" ); document.write( "4c = 65 - 9
\n" ); document.write( "4c = 56
\n" ); document.write( "c = 56/4
\n" ); document.write( "c = 14 is the shortest side
\n" ); document.write( "then
\n" ); document.write( "a = 2(14)
\n" ); document.write( "a = 28 is the longest side
\n" ); document.write( "and
\n" ); document.write( "b = 14 + 9
\n" ); document.write( "b = 23 is the middle side
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "Check this: 28 + 23 + 14 = 65 \n" ); document.write( "
\n" );
