First off, we are looking for the area of a poster that's in the shape of a rectangle. Since we are looking for the area of a rectangle, we need to know the formula for the area of a rectangle. The area of a rectangle is defined as Length times Width (L x W). Our length is 3 ft and our width is 2 ft. Given this information, we are ready to solve. (L x W) = A Plug in 3 for the length. (3 x W) = A Plug in 2 for the width. (3 x 2) = A 3 x 2 = 6. The area is 6 ft^2. I hope this helps!
