To solve this problem, we need to find the area of the rectangular flower bed, given in square feet.

Step-by-Step Solution:

1. Dimensions of the flower bed:

   • Length = $5$ yards
   • Width = $4$ yards

2. Convert yards to feet:

   • According to the conversion factors provided, $1$ yard = $3$ feet.
   • So, $5$ yards = $5 \times 3 = 15$ feet.
   • $4$ yards = $4 \times 3 = 12$ feet.

3. Calculate the area in square feet:

   • Area of a rectangle = length $\times$ width.
   • Thus, area = $15$ feet $\times 12$ feet = $180$ square feet.

Answer:

The area of the flower bed is 180 square feet.
