<PRE><B>Question 227743</B>
Find an algebraic expression. The perimeter of a rectangle, given that the length is x yards and the width is 10 yards shorter.


Step 1.  Perimeter P means adding up all four sides of the rectangle.


Step 2.  x-10 be the width of the rectangle since the width is 10 yards shorter.


Step 3.  P=x+x+x-10+x-10=4x-20


Step 4.  ANSWER:  Perimeter P=4x-20 (in yards).


I hope the above steps were helpful.
