Question 611416
We know that to find the area of the rectangle, you use {{{l*w=a}}}. But this is a word problem, we don't have measurements put out for us that easily. Let's write this in a mathematical notation.
Your rectangular ad is 5 inches long (l=5). Its width is 2 inches shorter than the length (l-2).
Since we know that l = 5, we can plug that in to get the width. {{{5-2=3}}}.
So, the length is 5 and the width is 3. {{{3*5=15}}}
The area of the rectangle is 15. :)
