Answer:
105 cm
Explanation:
You can separate this shape into 2. You can have a rectange and a right triangle.
Now, you have these, you find the area of each. The right triangle will be 15. Since the right angle triangle formula is b × h all over 2.
So, the base is 6 and the height is 5. 6 times 5 is 30, divided by 2 is 15.
The rectangle is b × h, so 15×6 is 90.
Add these two, which give you 105.
