This should be right because I checked it afterwards Width=W Length=2W-1 The equation is as follows W(2W-1)=21 [tex] 2W^{2} [/tex]-W=21 Subtract 21 from each side [tex] 2W^{2} [/tex]-W-21 Group them/put them in parentheses..can't think of the right word right now (2W-7)(W+3) -7=I7I You only do this for the first parenthese, 7÷2W=3.5 W=3.5 If W=3.5 then 2W-1⇒2×3.5-1⇒7-1⇒6 Length=6 If W=3.5 and L=6, then W(2W-1)=21 3.5(2×3.5-1)=21 Solve in parentheses first 3.5(7-1)=21 3.5(6)=21 3.5×6=21 The width is 3.5 The length is 6
