Answer: The required floor area of the room is 228 sq. ft.
Step-by-step explanation: We are given to find the floor area of a room if it measures 12 ft x 19 ft.
We know that
the floor of a room is always rectangular in shape and the area of a rectangle with length l units and width w units is given by
![A=lw.](https://img.qammunity.org/2019/formulas/mathematics/high-school/dne90rmf0bwt1ot4wun2ryfyculkaigucb.png)
For the given floor, l = 12 ft and w = 19 ft.
Therefore, the floor area of the room is given by
![A=lw=12*19=228~\textup{sq. ft}.](https://img.qammunity.org/2019/formulas/mathematics/high-school/nkhi5brjy07pz7wk97w8n66radkh45jrpi.png)
Thus, the required floor area of the room is 228 sq. ft.
