The area of a rectangle is 105mm^2 . The length is six millimeters less than three times its width. Find the dimensions of the rectangle.
a) Write the length in terms of its width(use w as the variable).
b) Write an equation using w for width.
equation:
c) What should the dimensions be?
a) The length is six millimeters less than three times its width, so we can write the length as 3w - 6.
b) The equation using w for width is:
(3w - 6) * w = 105
c) To find the dimensions of the rectangle, we need to solve the equation (3w - 6) * w = 105.
