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!
