Question

Find the cost of fencing a rectangular field are in the ratio 5:3 . If it's perimeter is 128 m. Find the dimension of the field

Answer 1

answer is 40m X 24m length and breadth respectively

Answer 2

field's ratio is 5:3
so perimeter will 2 ( 5x+3x ) = 128
  16x= 128
   x= 8
  so x  is 8m
 5 * 8 = 40m
3 * 8 = 24 m
so dimensions are =24m * 40m
