Answer 1

Draw a rectangle around the whole thing. Find the area. Now find the area of that notch cut out of the rectangle (hint: it's a rectangle and a triangle), and subtract that from the area of the big rectangle.

Answer 2

Or rectangle - trapezium

Answer 3

Yep, that works, too, but I figure that someone who needs advice on how to do this might be more comfortable with just rectangles and triangles. I'm happy to be proven wrong on that, of course :-)

Answer 4

Answer 5

Answer 6

Answer 7

Answer 9

Answer 10

Okay, good. Now let me look up the dimensions of that notch...

Answer 11

Do you know how to find the area of a trapezium, as kc_kennylau suggested, or do we need to break it down into a rectangle and a triangle?
