The shortest side is 30 yards longer than one-half of the longest side. THe second longest side is 2 yards shorter than the longest side. What is the length of each side? \n" ); document.write( "
Algebra.Com's Answer #111680 by Earlsdon(6294)![]() ![]() ![]() You can put this solution on YOUR website! Let's start by assigning letters to the three sides. \n" ); document.write( "A = longest side. \n" ); document.write( "B = second longest side. \n" ); document.write( "C = shortest side. \n" ); document.write( "The problem says that the perimeter (A+B+C) is 378 yards, so you can write: \n" ); document.write( " \n" ); document.write( "The problem also states that the shortest side, (C), is 30 yards longer than one half of the longest side, (A), so you can express this as: \n" ); document.write( " \n" ); document.write( "And, according to the problem statement, the second longest side (B) is 2 yards shorter than the longest side, so... \n" ); document.write( " \n" ); document.write( "Now you can make the following substitutions into the first equation: \n" ); document.write( " \n" ); document.write( "For B substitute A-2 and for C substitute \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "The sides are: \n" ); document.write( "A (the longest side) = 140 yards. \n" ); document.write( "B (the second longest side) = 138 yards. \n" ); document.write( "C (the shortest side) = 100 yards. \n" ); document.write( "Let's see if these add up to the given perimeter. \n" ); document.write( "140+138+100 = 378 \r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
