Question

A path 3.5 m wide runs inside along the boundary of a square field whose side is 65 m. Find the area of the path. Also find the cost of manuring the rest of the field at the rate of ₹25 per square metre

Answer 1

the answer is 5s⅔ this is the answer

Answer 2

Answer:

959 sq. m is the area of the path

Cost written in explanation

Step-by-step explanation:

Side of square field = 65 m

Width of path =  3.5 m

Area of the field= Side*Side

                          = 65*65

                          = 4225 sq. m

Area of the field including path = Side * Side

                                                    = (65+3.5+3.5) * (65 + 3.5+ 3.5)

                                                    = 65 + 7 * 65+7

                                                    =  72*72

                                                    =  5184 sq. m

Area of path= 5184 - 4225

                    = 959 sq. cm

Cost for manuring the rest of the field (excluding path) = area * rate

                                                                                           =  4225*25

                                                                                           = ₹ 105625

Cost for manuring the rest of the field (including path) = 5184 * 25

                                                                                          = ₹ 129600

Cost for manuring the path only = 959 * 25

                                                     =  ₹ 23975
