how to find the perimeter of a rectangular flower bed

Question

A rectangular flower bed is 3n5o meters wide, and 5n5o meters long.  What is the perimeter of the flower bed?

There are symbols on the n's & o's but I can't type them on my computer

 

Answer 1

The perimeter is basically the outline of the shape.  The perimeter of a rectangle is given by P=2l+2w, where l is the length and w is the width.  Thus, the perimeter of the flower bed would be given by P=2(3n5o)+2(5n5o).  In this instance, you could distribute to get 6n10o+10n10o.
