Question

The cost of cultivating rectangular field at rupees 35 per square metre is rupees 71400 if the width of the field is 40 meters and find its length also find the cost of fencing the field at 50 rupee per metre.

Answer 1

➡HERE IS YOUR ANSWER⬇

Area of a rectangle = Length × Width

Given :

Width = 40 m

Then, by the given condition

Area of the rectangular field = (Total cost of fencing)/(Cost of fencing per metre)

or, Length × Width = 71400/35

or, Length × 40 = 2040

or, Length = 2040/40

or, Length = 51

So, the length of the rectangular field = 51 m

Now, to fence a field is to find its perimeter.

Perimeter of the rectangular field

= 2 × (Length + Width)

= 2 × (51 + 40) m

= 2 × 91 m

= 182 m

Therefore, total cost of fencing at Rs 50 per metre

= Rs (182 × 50)

= Rs 9100
