Question 710022:
A rectangles width is one-seventh its length,and its perimeter is 192 m. Find the dimensions of the rectangle. Answer by checkley79(3341) (Show Source):
You can put this solution on YOUR website! W=L/7
P=2L+2W
192=2L+2(L/7)
192=2L+2L/7
192=(2L*7+2L)/7
192=(14L+2L)/7
192=16L/7
16L=192*7
16L=1344
L=1344/16
L=84 m. ANS. FOR THE LENGTH.
W=84/7=12 m. ANS. FOR THE WIDTH.
PROOF:
192=2*84+2*12
192=168+24
192=192
