Answer:

67.5 mm²

Step-by-step explanation:

Alright, we're going to make 3 different smaller shapes

Shape (triangle)

  1. a=1/2(b)h
  2. a=1/2(5(3)= 7.5

Shape (skinny rectangle)

  1. a=l·w
  2. a=2·9= 18

Shape (bigger rectangle)

  1. a=l·w
  2. a=7·6= 42

Add them all together

42+18+7.5= 67.5
