The perimeter of a triangle is 51 cm. The longest side is twice the length of the shortest side. The third side is 3 cm longer than the shortest side. What is the length to each side?
\n" ); document.write( "-----------
\n" ); document.write( "Let shortest side be \"x\".
\n" ); document.write( "Then longest side is \"2x\".
\n" ); document.write( "And 3rd side is \"x+3\".
\n" ); document.write( "EQUATION:
\n" ); document.write( "x+2x+x+3=51
\n" ); document.write( "4x+3=51
\n" ); document.write( "4x=48
\n" ); document.write( "x=12 cm (length of shortest side)
\n" ); document.write( "2x=24 cm (length of longest side)
\n" ); document.write( "x+3=15 cm (length of 3rd side)
