So we have (impossible) or . Solve for L.
Without being given any extra information, like what the original or resulting areas or perimeters actually were, you can't solve for W.
Hi.
So I'm looking for help with this geometry problem. It is:
the L of the rectangle is decreased by 2.4cm . The W of the rectangle is increased by 30%. As the result, the area of the rectangle grew 4%. Find the original L and W.
First i did an equation (L - 2,4cm) x 1,3W = 1.04LW and from there i got that the L is 12. now i don't know what to do on as every equation or whatever i do with the information
I keep ending up with things like W = W or i get the answer of L again aka I'm stuck. Please help.
Thank you.

you did a mistake there on the action in line 2-3. you deducted 0.04 from 1.3, not 1.04, so it should result in 0.26L - 3,12 = 0, but that doesnt matter. the problem is taken from 2009 test from my uni which if done >75% grants you "done" or w/e in "basic math". i'm gonna have to do it too, but i hope it's their mistake then. it should be done with pre-uni knowledge.
Thank you for pointing out my error, it's been edited
Like I said, without any extra information (like knowing what the original area or perimeter of your rectangle were), any value of W will work.
