I like area questions.

On the left we have a triangle, base apparently 9 cm, height 7 cm.

In the middle it's a 3 cm by 9 cm rectangle.

Then it's a parallelogram, base 9.  We have to figure out the height; it must be 16 - 7 - 3 = 6 cm.

Adding up the areas,

A = (1/2) 9×7 + 3×9 + 6×9 = 112.5 sq cm

Answer: 112.5 sq cm
