Answer:

  64.5 square inches

Step-by-step explanation:

The area of each of the two triangles can be found from the formula ...

  A = (1/2)bh

left triangle

  A = (1/2)(9.8 in)(8.6 in) = 42.14 in²

right triangle

  A = (1/2)(5.2 in)(8.6 in) = 22.36 in²

Total shaded area is the sum of the areas of the two triangles:

  (42.14 +22.36) in² = 64.5 in²
