Answer:

30cm2

Step-by-step explanation:

first find area of triangle

A = 1/2 *b*h

A = 1/2 * 9 * (4 + 3 +1)

I got the 3 from the other side of the cut out rectangle.

1/2 * 9 * 8 = 36

next find area of cut out rectangle

A = l * w

A = 3 * 2 = 6

Last, subtract area of triangle - area of cut out rectangle

36-6 = 30cm 2
