Answer:

  (c)  180 cm²

Step-by-step explanation:

Maybe you want the area of the trapezoid. That is given by the formula ...

  A = (1/2)(b1 +b2)h

where b1 and b2 are the base lengths, and h is the height.

Here, the top base is marked 16 cm, and the bottom base is shown as 4 cm longer, so is 20 cm.

  A = (1/2)(16 cm +20 cm)(10 cm) = 180 cm²
