Question

Answer 1

Answer:

Length of fence = 41.2 m, Cost of painting= 3090 Rs

Step-by-step explanation:

Given : Length of the paddy field = 11.7 m

            Breadth of the paddy field = 8.9 m

             Rate of painting = 75 Rs/m

              Length of fence = ?

             Cost of painting = ?

Solution : Length of fence = perimeter of field

                                           = 2 ( L + B)

                                           = 2 x ( 11.7 + 8.9)

                                           = 2 x 20.6

                                           = 41.2 m

             Cost of painting = Rate of painting x length of fence

                                        = 75 x 41.2

                                        = 3090 Rs
