Today I learned more about area and calculating area. Because of this learning I can now calculate area and not make the silly mistake I made in maths olympiad.
This is the mistake I made:
Since I had not done area for a while I calculated the sides but then I took 50 to 5 and 70 to 7 and then it was 7 times 5 = 35 so then i added on a zero but i should have added on two zeros. so the real answer is 3500!!!
The next step in my learning is to.....
1. Practise my area a little every now and again so i do not forget how to calculate area.
2. To get better at calculating area on shapes like the one in the picture.
