Question 286962: the length of a rectangular parking lot is 10 meters less than twice its width, and the perimeter is 370 meters, find the length of the rectangular parking lot.
L = ____ meters Answer by checkley77(12844) (Show Source):
You can put this solution on YOUR website! L=2W-10
2L+2W=PERIMETER
2(2W-10)+2W=370
4W-20+2W=370
6W=370+20
6W=390
W=390/6
W=65 ANS. FOR THE WIDTH.
L=2*65-10
L=130-10
L=120 ANS. FOR THE LENGTH.
PROOF:
2*65+2*120=370
130+240=370
370=370
