Answer:
3/10
Step-by-step explanation:

Answer:
As Given, x+y=w+z
To Prove: AOB is a line or x+y=180
∘
(linear pair.)
According to the question,
x+y+w+z=360
∘
∣ Angles around a point.
(x+y)+(w+z)=360
∘
(x+y)+(x+y)=360
∘
∣ Given x+y=w+z
2(x+y)=360
∘
(x+y)=180
∘
Hence, x+y makes a linear pair.
Therefore, AOB is a straight line

Step-by-step explanation:
look at the given picture
The figure on the top left is a triangle with base 11 and height 8, for an area of

Immediately below, we have a rectangle with dimensions 11 and 9, for an area of

Moving to the right, we have a parallelogram with base 9 and heght 11, which again has height

Finally, the rightmost figure is a triangle with base 8 and height 9, for a total of

Sum these areas and you'll get the total area
