document.write( "Question 124095: The length of a rectangular garden is 7 ft. more than twice its width. If the perimeter of the garden is 56 ft., find the width of the rectangle. \n" ); document.write( "
Algebra.Com's Answer #90994 by PBMathandscience(9) ![]() You can put this solution on YOUR website! The perimeter of a rectangle is 2x(Length + Width). Let W be the width. Then the length is W+7. The resultant equation is:\r \n" ); document.write( "\n" ); document.write( "56=2*((W+7)+W)\r \n" ); document.write( "\n" ); document.write( "Divide both sides by 2;\r \n" ); document.write( "\n" ); document.write( "28=W+7+W\r \n" ); document.write( "\n" ); document.write( "Subtract 7 from both sides:\r \n" ); document.write( "\n" ); document.write( "21 = 2*W\r \n" ); document.write( "\n" ); document.write( "Divide by 2\r \n" ); document.write( "\n" ); document.write( "10.5=W\r \n" ); document.write( "\n" ); document.write( "Check: 2*((10.5+7)+10.5)=2*(17.5+10.5)=2*(28)=56.\r \n" ); document.write( "\n" ); document.write( "Solution checks.\r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
