The length of a rectangle is 6 ft more than its width. The perimeter of the rectangle is 68 ft. What are the dimensions of the rectangle?
Let w represent the width of the rectangle.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Let W represents the width of the rectangle.
Then its length is W+6.
Then the perimeter is 2W + 2(W+6).
Then for the perimeter you have an equation
2W + 2W + 12 = 68.
4W = 68 - 12,
4W = 56,
W = = 14.
Answer. The width is 14 ft, the length is 20 ft.
