Answer:
1300 squared meters
1300 m^2
Explanation:
What I would do personally is that I would find the entire area of the entire thingie at once and subtract the white space.
So the total height is 30 meters and the width is 50 meters. 30 times 50 is 1500. Then the height of the white space is 5 meters and the width is 40 meters.
5 times 40 is 200.
1500 - 200 = 1300
Hence 1300 squared meters.
It is squared meters and not meters since it is talking about the area and not the length/width pythagorean concept of convection (I dunno what that is), but 1300 meters squared is something completely different and so is 1300 meters, so make sure that you put squared meters instead of something else like inches lol.
1300 squared meters.
Hope this helps!
