Answer» Let length of the rectangular plot in meters ` = 11x` The, breadth of the rectangular plot in meters ` = 4x` `:. ` Perimeter of the rectangular plot in meters `(P) = 2(11x+4x) = 30x` Total cost of fencing the plot ` = 75000` RsRate of cost ` = 100` Rs per meter So, perimeter`(P) = 75000/100 = 750` meter `:. 30x = 750` `=> x = 25` `:.` Length of the rectangular plot ` = 11**25 = 275m` Breadth of the rectangular plot ` = 4**25 = 100m` |
