To find the area of the poster in square feet:

1. The poster dimensions are given as:

   • Length = 36 inches
   • Width = 24 inches

2. First, convert these measurements to feet, as 1 foot = 12 inches:

   • Length in feet: $36 \, \text{inches} \div 12 = 3 \, \text{feet}$
   • Width in feet: $24 \, \text{inches} \div 12 = 2 \, \text{feet}$

3. Now, calculate the area in square feet: $\text{Area} = \text{Length} \times \text{Width} = 3 \, \text{feet} \times 2 \, \text{feet} = 6 \, \text{square feet}$

So, the area of the poster is 6 square feet.
