to find the area of an irregular shape, you have to divide it into multiple squares/rectangles, calculate those areas and add them together.
5. 3cm x 4cm = 12cm , 5cm x 8cm = 40cm
final answer: area = 52cm
6. 3m x 2m = 6m , 3m x 2m = 6m , 4m x 9m = 36m
final answer: area = 48m
7. this appears to be 4mm x 3mm , but 6 times , which comes out to 12mm x 6
final answer: area = 72mm
8. 11cm x 3cm = 33cm , 7cm x 6cm = 42cm
final answer: area = 75cm
