Identify \(\text{every}~\text{card}\) whose area uses the trapezoid area formula.

Card 1: a shape with \(\text{one}~\text{pair}\) of parallel sides measuring \(14~m\) and \(8~m\) and a height of \(5~m\)
Card 2: a shape with base \(11~\text{cm}\) and height \(7~\text{cm}\) and opposite sides parallel
Card 3: \((1/2)~\times~(b_{1}~+~b_{2})~\times~h\)
Card 4: a banner shaped like a triangle with base \(16~\text{in}\). and height \(9~\text{in}\).
Card 5: a field shaped like a trapezoid with bases \(20~\text{yd}\) and \(12~\text{yd}\) and height \(9~\text{yd}\)
Card 6: a composite figure split into a rectangle and a triangle, where the total area is found by adding the \(\text{two}~\text{parts}\)
Card 7: a table top shaped like a rectangle that is \(15~\text{ft}\) by \(4~\text{ft}\)
Card 8: a trapezoid whose area is described by averaging the \(\text{two}~\text{bases}\) and multiplying by the height
