A park, in the shape of a quadrilateral `ABCD,` has `/_C=90^o ,\ A B=9 m ,\ B C=12 m ,\ C D=5 m a n d\ A D=8 m`. How much area does it occupy?

Explanation

To find the area of the quadrilateral park ABCD, we can divide it into two triangles: triangle BCD and triangle ABD.

### Step 1: Calculate the area of triangle BCD
Since angle C is 90 degrees, we can use the formula for the area of a right triangle:

\[ \text{Area}_{BCD} = \frac{1}{2} \times \text{base} \times \text{height} \]
