Answer 1

Answer:

given ratio of length and breadth = 11:4

let length = 11x , breadth = 4x

its perimeter = 2(l+b) = 30x

given it costs 100/- per meter and total cost is Rs. 75000

cost of fencing = perimeter × cost per metre

75000 = 3000x

=> x = 25

∴ length = 11x = 11(25) = 275m

breadth = 4x = 4(25) = 100m
