<PRE><B>Question 215445</B>
A rectangle is 6 times as long as it is wide. The perimeter is 100 cm. Find the dimensions of the rectangle. Round to the nearest tenth if necessary.


Step 1.  Let w be the width and 6w is the length.


Step 2.  Perimeter P means adding up all the 4 sides of the rectangle. Then,


{{{P=100=w+w+6w+6w=14w}}}


{{{100/14=14w/14}}}


{{{w=100/14=7.1}}}


With w=7.14, then 6w=42.9


Step 3.  The dimensions of the rectangle are 7.1 cm and 42.9 cm.


I hope the above steps were helpful.
