Assuming that the bathroom floor is a rectangle, the area of the rectangle is equal to the product between the width and length:
[tex]A=wl[/tex]Given that the area is 24ft² and the width is 4ft, you can calculate the length of the rectangular floor as follows:
[tex]\begin{gathered} A=wl\to l=\frac{A}{w} \\ l=\frac{24}{4} \\ l=6ft \end{gathered}[/tex]The length of the bathroom floor is 6ft.
Now you can calculate its perimeter by applying the formula:
[tex]\begin{gathered} P=2l+2w \\ P=2\cdot6+2\cdot4 \\ P=12+8 \\ P=20 \end{gathered}[/tex]The perimeter of the bathroom floor is 20 feet
