Dimensions of his room as follows :
Length of his room = 13 feet
Width of his room = 12 feet
We need to find the square feet of carpet which is used to cover the floor of his room.

Area of rectangle = Length × Breadth
So, Area of his room becomes
[tex]13\times 12\\\\=156\ sq.\ feet[/tex]
Hence, 156 square feet of carpet would be needed to cover the floor in his room.
