Answer:

The area of the traingle AOB is 30 (Rounded up result)

Explanation:

7.8 cm and 10 cm.

10/2= 5 cm

Then Reversed Pitagora's Formula:

Square root of the calc "(7.8^2)-(5^2)" = 60,84 - 25 = 35,84

Then Square root of 35, 84 is 5,98.

5.98 is the height of the triangle AOB

With the height we can calculate the area

We use the formula (B*H)/2

So is (10*5,98)/2, that makes 29,9

Just round up to 30 and that's the area.
