Question

What is the total area of the garden

Answer 1

The yellow area is 4 * 3 = 12 ft^2

The green area is a trapezoid

area = 1/2 (top + bottom) * height

         = 1/2 (2+4) * 1

          = 1/2 (6) * 1

          = 3 ft^2

total area = yellow area + green area

                = 12 + 6

                 =  18 ft^2

Answer 2

18ft^2 is your answer
