Algebra.Com's Answer #348080 by simranb(63)![]() ![]() You can put this solution on YOUR website! Hi,Hope you find your answer, \n" ); document.write( "Let the width be x \n" ); document.write( "then the length would be x+3 \n" ); document.write( "Then Perimeter=2(l+b)=34 \n" ); document.write( "2(x+x+3)=34 \n" ); document.write( "2(2x+3)=34 \n" ); document.write( "4x+6=34 \n" ); document.write( "4x=34-6 \n" ); document.write( "4x=28 \n" ); document.write( "x=28/4 \n" ); document.write( "x=7 \n" ); document.write( "Then the length =x+3 \n" ); document.write( " =7+3=10m \n" ); document.write( "Width = x =7m \n" ); document.write( "Area = l * b \n" ); document.write( " = 10 * 7 \n" ); document.write( " = 70sqm \n" ); document.write( "Cheers! \n" ); document.write( "Simran \n" ); document.write( " |
