<PRE><B>Question 699481</B>
&lt;br&gt;&lt;font face=&quot;Tahoma&quot;&gt;The area of a rectangle is given by this simple formula:&lt;br&gt;

{{{A=l*w}}}&lt;br&gt;

where l is the length of the rectangle,&lt;br&gt;

and w is the width of the rectangle.&lt;br&gt;

Thus, we have:&lt;br&gt;

{{{A=6.25*9.75}}}&lt;br&gt;

{{{A=60.9375}}}&lt;br&gt;

So the area of our rectangle is 60.9 {{{ft^2}}}&lt;br&gt;

This is because we round the answer to the lowest number of significant digits&lt;br&gt;

in either of our original two numbers.&lt;br&gt;

There are 3 significant digits in both numbers,&lt;br&gt;

so we round our final answer to 3 significant digits as well.&lt;br&gt;

Also, in most cases, the length of a rectangle will be longer than its width,&lt;br&gt;

but that is just a practical concern, it does not affect the area, nor the perimeter.&lt;br&gt;

I hope this helps!  Keep practicing!  :)&lt;br&gt;
