Question

ratio between lenghth and the breadth of a rectangular feild is 9:4 rs 14400 are spent on implementation in rs 4 /sq m what is breadth​

Answer 1

Step-by-step explanation:

let L is the length and W is breadth of a rectangle field;

9:4 = L/W;

L = 9w/4;

area of field = L*W = 9w2/4;

total cost/per sq. m cost = 14400/4 = Area 9w²/4;

Bye solving this we get

14400 = 9 w2;

(12*10/3)² = w2;;

w = 40;

L = 9w/4 = 9*40/4 = 90 m
