The perimeter of a rectangle is 194 cm. the length of the rectangle is three centimeters less than four times the size of width. what is the length, l, and width, w, of the rectangle?

Given that:
Perimeter=194 cm
Width=w
Length, L= 4w-3
Formula for perimeter of rectangle:
P=2(L+W)
Put values
194=2(4w-3+w)
194=2(5w-3)
Divide both sides by 2.
97=5w-3
Add 3 to both sides
100=5w
w=20

So length= 4 (20) -3 = 80-3 =77 cm
and width= 20 cm

Length=77 cm and width=20 cm

Ifound this on google “that means that the graph of a function with direct variation has these features: it is a straight line: because the slope is the ratio y/x = k. it passes through the origin (0,0): because y = kx = k (0) = 0.” i hope this you for what your looking for
