Algebra.Com's Answer #584280 by macston(5194) You can put this solution on YOUR website! W=width; L=length=6W; P=perimeter=84yds; A=area \n" ); document.write( "P=2(L+W) Substitute for L. \n" ); document.write( "84yds=2(6W+W) \n" ); document.write( "84yd=12W+2W \n" ); document.write( "84yd=14W Divide each side by 14. \n" ); document.write( "6yd=W The width of the rectangle is 6 yards. \n" ); document.write( "L=6W=6(6yd)=36 yards The length is 36 yards. \n" ); document.write( "A=L*W \n" ); document.write( "A=36yd*6yd=216 sq yd ANSWER: The area is 216 square yards. \n" ); document.write( " |
