First you should find the area of the rectangle in the middle. A: 9 x 6 = 54 Then you can find the area of the triangle on the right. A: 6 x 5 = 30/2 = 15 Then you can do the triangle on the right. 11-9 = 2 A: 2 x 6 = 12/2 = 6 Then you can add it all together. 15 + 6 + 54 = 74 So the area of the irregular shape is 74.
Well i would look at the trapezium on the left (i would forget the first dashed line) and use 1/2 a + b × h to work out the area of a trapezium. So you would do 1/2 of 9+11 × 6 which is 60cm^2. Then I would work out the area of the triangle which is 1/2 b×h. You would do 1/2 of 6×5 which is 15cm^2. Add 60 and 15 and you get 75cm^2 Ok looking at the other persons I think I did it wrong
