Question

The length of a rectangle is 12 meters less than 6 times the width. If the perimeter of the rectangle is 256 meters, find the length and the width of the rectangle.

Answer 1

width=20m

length=108m

Explanation:

w=x

l=6x-12

p=2(w+l)

256=2(x+6x-12)

256=2(7x-12)

256=14x-24

256+24=14x

280=14x

x=280/14

x=20

recall,

l=6x-12=6*20-12=120-12=108
