check your typing, right now your post makes no sense.
"... find the length if its worth (16x^2y^2) dm ?? "
did you mean , if it width is .... ?
In that case just divide 256x^4y^4-169c^4y^4 by 16x^2 y^2 to get
16x^2 y^2 - 169c^4 y^2/(16x^2)
btw, the units for the area would be dm^2 , not dm
if the area of the rectangle is 256x^4y^4-169c^4y^4 dm find the length if its worth (16x^2y^2) dm ??
Thankss :)
