Example Question #73 : How To Find The Perimeter Of A Rectangle

Find the perimeter of a rectangle with width 4 and length 6.

 

Possible Answers:

Correct answer:

Explanation:

To solve, simply use the formula for perimeter. Thus,

If this formula is hard to remember, simply draw a diagram and add up the sides. Remember, there are two widths and two lengths per rectangle so you get w+w+l+l which is equivalent to the formula above.
