Question

the length and breadth of a rectangular field are in the ratio 9 is to 5 if the area of the field is 14500 square metres find the cost of sending the field with a sense at the rate of 3.2 5 rupees per metre

Answer 1

let the l and b be 9x and 5x
9x * 5x = 14500
45x*X = 14500
X*X = 45 x square is equal to 14500 so then calculate the value of x and to the value of x and length and breadth and then find the perimeter and then multiply the perimeter with 3.5 u will get the answer
