Hey guys, I've got about 25 word problems that I'm trying to trudge through, I'm down to two that I cant figure out, and I know they're really simple!!!
A rectangular lot is surrounded on all sides by a driveway 3 yards wide. The lot is twice as long as it is wide. If the area of the lot and driveway together is 216 sq. yards, find the dimensions of the lot.
I've got it set up as an area problem (A=L*W) but it seems to be asking for the perimiter (P=2L+2W) and I'm just stuck! I cant get it set up right (2x-3 or 2x+3 or just 2x for L?) I would appreciate any help, once I get this one done I'll have the assignment finished!
(Thanks!)
