Answer:

{105cm}^{2}

Step-by-step explanation:

Im assuming it's asking for the area of the shape.

We need to break the shape into two sections as shown in the picture. First we find the area of the rectangle (9×10)

90cm^2

15cm^2

Now add up the two amounts.

p = 92

Vertical angle is m, which is 92.

Hope this helped.
