Algebra.Com's Answer #668781 by jorel555(1290)![]() ![]() ![]() You can put this solution on YOUR website! Let w be the width of the rectangle. Then the length of the rectangle is 2w+10. So: \n" ); document.write( "w(2w+10)=48 \n" ); document.write( "2w²+10w-48=0 \n" ); document.write( "w²+5w-24=0 \n" ); document.write( "(w+8)(w-3)=0 \n" ); document.write( "w=3 or -8. \n" ); document.write( "Throwing out the negative result, we get the width to be 3 ft., and the length to be 16 ft. ☺☺☺☺. \n" ); document.write( " |
