Algebra.Com's Answer #38216 by stanbon(75887)![]() ![]() ![]() You can put this solution on YOUR website! 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) \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( " |
