Answer 2

Answer:

The cost of cultivating will be Rs. 640

Step-by-step explanation:

The length of a rectangular field is given to be 16 m

Also, it is given that the breadth is half its length

breadth = length /2

             = 16/2

            = 8 m

We will first find the area of the field

area = length × breadth

        = 16 × 8

        = 128 m²

rate of cultivating is 5 per m²

so, cost of cultivating = area × rate

                                   = 128 × 5

                                   = 640
