Frances is sewing a border around 2 rectangular tablecloths that each measure 9 feet long by 6 feet wide. if it takes her 3 minutes to sew on 1 inch of border, how many minutes will it take her to complete her sewing project? write an expression, and then solve.

The perimeter of a rectangle is - 2 x (length + breadth). 

Also, 1 feet = 12 inches.

So, the dimensions of the tablecloth are 108 inches long by 72 inches wide. So, the total perimeter of the table cloth is --> 2 x (108 + 72) = 360 inches. 

So, time taken for 1 tablecloth = 360 x 3 = 1080 minutes.

And, Time taken for 2 tablecloths = 1080 x 2 = 2160 minutes.

So, to complete her sewing project, Frances will take a total of 2160 minutes (36 hours).
