The area for a trapezoid is A=1/2(b*1+b*2)h Your base is your two parallel sides, and your parallel sides in this case is 5cm and 11cm, so that means your bases are 5&11. Your height is 4. A=1/2(5+11)4 In order to do this you need to do the distributive property first. 1/2 x 5 = 2 1/2 1/2 x 11 = 5 1/2 Then next you need to do: 2 1/2 + 5 1/2 = 8 The last step is to do: 8 x 4 = 32 SO THE ANSWER IS 32.
