Answer:
90
Step-by-step explanation:
Hi!
What we have over here is a composite figure.
Basically, it's made up of different shapes
We can either make a rectangle by making a horizontal line from the point in between 6 mm and 5 mm
Or we can make a rectangle by going verticle from the point in between 6 mm and 5 mm
Either way, we have two rectangles now, and we can use our formula to find the area.
For the first example, we would do:
Then we add the two areas of the two rectangles:
For the second example, we would do:
Just cut the figure into shapes you can calculate the area of and you should be good to go!
