 Answer: Therefore, his son and daughter got Rs 200.
Step-by-step explanation:
6 kg of rice = 75*6 = Rs 450
2 packets of oil = RS 2*125 = RS 250
now total money he spent = Rs 450 + Rs 250 + Rs Rs 3,300
                                              = Rs 700 + Rs 3,300
                                              = Rs 4000
Money left = Rs 4,400-Rs 4000 = Rs 400
so 
400/2 = Rs 200

You need to split the shape into two then measure the shapes like trapezoids use a+b/2(h) for the formula
