Algebra.Com's Answer #454941 by Cromlix(4381)![]() ![]() You can put this solution on YOUR website! A perimeter = 2 lengths + 2 breadths \n" ); document.write( "If the length is 1.5 more than the \n" ); document.write( "breadth, then make length = (x + 1.5) \n" ); document.write( "This perimeter = 2 (x) + 2(x + 1.5) \n" ); document.write( " = 2x + 2x + 3 \n" ); document.write( " = 4x + 3\r \n" ); document.write( "\n" ); document.write( " 4x + 3 = 63 \n" ); document.write( " 4x = 60 \n" ); document.write( " x = 15 \n" ); document.write( "So breadth = 15 and length = 16.5 \n" ); document.write( " \n" ); document.write( " |
