To find the area of the poster in square feet, we need to convert the given dimensions from inches to feet.
Since there are 12 inches in 1 foot, the length of the poster in feet is: 36 inches / 12 inches/foot = <<36/12=3>>3 feet.
Similarly, the width of the poster in feet is: 24 inches / 12 inches/foot = <<24/12=2>>2 feet.
The area of the rectangle is found by multiplying the length and width, so:
Area = 3 feet * 2 feet = <<3*2=6>>6 square feet.
Therefore, the area of the poster is 6 square feet. Answer: \boxed{6}.
