Question

rajan has a square feild of area 9 hectares he wants to fence it find the cost of erecting if the cost of fencing is 40 per metre
​

Answer 1

Answer:

Step-by-step explanation:

Firstly we should convert hectare into meter

1 hectare = 10000 meters

9 hectare = 9 × 10000 meters

= 90000 meters

Area of square = S×S

90000= S²

Root 90000 = S

300 = S

Therefore side is 300 m

To find fencing we should find perimeter

Perimeter = 4× S

= 4×300

= 1200 m

Cost of fencing 1 m = rupees 40

Cost of fencing 1200 m= 40 × 1200

=48000 rupees
