Answer» Given: LENGTH of the plot = 125 m Breadth of the plot = 78 m Area of plot ABCD=Length×Breadth =125×78 =9750m Length of the plot including the path =(125+3+3)m=131m Breadth of the plot including the path =(78+3+3)m=84m Now, Area of plot PQRS including the path = Length×Breadth=(131*84) =11004m Area of path = Area of plot PQRS − Area of plot ABCD=11004-9750 =1254m COST of gravelling =RS 75 per m Cost of gravelling the whole path =RS (1254×75)=RS 94050 Hence, cost of gravelling the path is RS 94050. solution |
