5. Area of square = S X S Area of rectangle = L X W Area of rhombus = b x h

6. Area of parallelogram = b x h b h b h

8. ------------------------- Middle base Area of trapezium = M.b. x h

9. 1) A trapezium in which the length of the two parallel bases are 7 cm. and 9 cm. and its height is 5 cm.. Find its area.
