hmm, would prefer to work it out with you but i guess i can just show my work if you are not here c:
OpenStudy (jennyrlz):
ok so we know the equation to find the are of a rectangle is: Height x Width
OpenStudy (jennyrlz):
now there are two ways to go about doing this, the "safe" way to set it up into a n equation. While this method takes longer you will have less of a chance of making mistakes!

so we can set it up like x-5=2x
OpenStudy (jennyrlz):
2x-5=x*

then by simple multiplication or division, i instintly arived at 11 x 3
OpenStudy (jennyrlz):
3 x 2 = 6
6 + 5 =11
or 11 - 5 = 6
