<PRE><B>Question 215459</B>
The length is 14 cm, width is 8 cm. what is the expression for the perimeter of a rectangle?


Step 1.  Perimeter P means that we add up all four sides of the rectangle.


Step 2.  Let W be the width and L be the length.


Step 3.  Then P=W+W+L+L=2W+2L=2(W+L)


Step 4.  Given L=14 cm and W=8 cm, then P=2(14+8)=44.


Step 5.  ANSWER:  The perimeter is 44 cm where perimeter P is found as P=2(W+L).


I hope the above steps were helpful.
