Algebra.Com's Answer #38353 by tutorcecilia(2152) You can put this solution on YOUR website! 1)Use the formula for the perimeter of a rectangle: \n" ); document.write( "Perimeter = 2(length + width) \n" ); document.write( "Width= 3 feet \n" ); document.write( "Length = (3)(1/2)=1.5 feet \n" ); document.write( "P=2(1.5+3) \n" ); document.write( "P=2(4.5) \n" ); document.write( "P=9.0ft \n" ); document.write( " \n" ); document.write( ". \n" ); document.write( "2)Use the percent formula: \n" ); document.write( "Part/Whole=Percent/100 \n" ); document.write( "Plug-in the values: \n" ); document.write( "30/1200=Percent (x)/100 \n" ); document.write( "Cross-multiply \n" ); document.write( "(30)(100)=(1200)(x) \n" ); document.write( "3000=1200x [Solve for x] \n" ); document.write( "3000/1200=x \n" ); document.write( "2.5%=x \n" ); document.write( " \n" ); document.write( " |
