Question

The cost of cultivaçting a rectangular at 35 rupees per square metre is 71400 rupees if the width of the field is 40cm. find its length also find the cost of fencing the field at 50rupees per meter

Answer 1

Answer:

Step-by-step explanation:

Cost of cultivation = 35 per metre

Total cost of cultivation = 71400

Area of field = 71400/35

2040m^2

Now,

Width = 40 cm

That is , 0.4m

Area = l×b

L = area/breadth

L = 2040/0.4

L = 5100m

Now, cost of fencing per m. = 50rs

Total cost = perimeter × 50rs

Total cost = 2(l+b) × 50rs

Total cost = 2(51000.4) × 50

Total cost = 5100040rs

Hope it helps :)
