Question

mathmale · Answer

It may help you to sketch this rectangle.
Next, you'll want to label each side.

Represent the length by l.  Then, following "the length of a rectangle is 6 m more than its width, w," write a formula for l in terms of w.

Write out the general formula for perimeter of a rectangle:  P = 2L + 2W

substitute your own l and w.

Compute P.
