Given \(3\) feet wide is exposed on all sides. Hence all \(4\) sides will have \(3\) feet gap.
Length of floor \(= 20\)
Length of rug \(= 20 - 3 - 3 = 14\)
Width of floor \(= 16\)
Width of rug \(= 16 - 3 - 3 = 10\)
Hence dimensions of rug \(= 10\) by \(14\)
Answer: A
Length of floor \(= 20\)
Length of rug \(= 20 - 3 - 3 = 14\)
Width of floor \(= 16\)
Width of rug \(= 16 - 3 - 3 = 10\)
Hence dimensions of rug \(= 10\) by \(14\)
