substitute 18.9 for w and solve for l in the second equation
how do i get the lenght??
what do you get
in the second equation lenght times width equalls area subtitute 18.9 then solve for l by dividing both sides of the equation by w
is it right?? i get 27.3 for the leght... can you please check it if it is right... :d
yes
now substitute l and w in the first equation to get the perimeter.
