Question

Find the breadth of a rectangular field whose length is 120 m and cost of turfing it at ₹15 per m² is ₹1,35,000​

Answer 1

Answer:

75 m.

Step-by-step explanation:

Let,

Length= 120 m

Cost of turfing= ₹15/m²

Total cost= ₹1,35,000

∴Total area= (1,35,000÷15) m²

                  = 9000 m²

∴Breadth= (9000÷120) m

               = 75 m

∴Ans, Breadth is 75 m.

Answer 2

Answer:

Total cost of turfing = ₹135000

Rate of turfing = ₹15 per m²

$area \: of \: the \: rectangular \: field \: = \\ \\ \frac{total \: cost \:of \: turfing }{rate \: of \: turfing} = {9000m}^{2}$

$breadth \: of \: the \: rectangular \: \: field \: = \: \\ \\ \frac{area}{length} = \frac{9000 {m}^{2} }{120m} = 75m$

✅ hence the breadth of the rectangular field is 75 m.
