Finding the area of compound shapes

[@mahmedabdirahman4831]

thank for your video post sir but i have a question in your two first questions once you add thr first question in area of rectangle +area of triangle and second question you subtract the area of rectangle - area of triangle what is the difference

When can I add and when can I subtract at the end of the solution?

Using just about and probably are not reassuring when it comes to solving math problems. I need steps and facts.

Very Good but I reccomend getting a new mic because my ears are dead and I am using pretty high quality headphones

Hi I'm stuck on a past paper question for my homework. It goes like this "The areas of the colours red, white and blue on the Union Jack flag are in the ratio 10:8:7. One large flag has an area of 200m2. As an estimate, what area of this flag is coloured blue?" How do I work this out? Your videos are a huge help for GCSE's thank you =)

That is a ratio question, see this video: kzbin.info/www/bejne/qaCVpHRmotukfKs
