The Perimeter of a rectangle is 194 cm. The length of the rectangle is three centimeters less than four times the size of width.

Rus_ich [418]

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

Answer: Length=77 cm and width=20 cm
