the length of a rectangle is 2 less than 3 times its width. the perimeter of the rectangle is 36 inches.determine the dimensions of the rectangle.
----
Let the width be "x":
Then the length is "3x-2":
----------------------------
Perimeter = 2(length + width)
36 = 2(3x-2 + x)
18 = 4x-2
4x = 20
x = 5 inches (width)
----
3x-2 = 13 inches (length)
-----------------------------
