Look at the statement given below: I. A parellelogram and a rectangle on the same base and between the same parallels are equal in area. II. In a ||gm ABCD, it is given that AB = 10 cm. The altitudes DE and AB and BF on AD being 6 cm and 8 cm respectively, then AD = 7.5 cm. III. Area of a ||gm =(1)/(2)xx "base" xx "altitude." Which is true?
