Fencing the compound of a house costs rupees 5452.If the rate is rupees 94 per metre, find the perimeter of the compound .If the breadth is 10 m , find its length

Answer 1

Answer:

Step-by-step explanation:

perimeter of compound = $\frac{total cost}{cost per metre}$
                                        = $\frac{5452}{94}$
                                        = 58 metres

perimeter of compound = l+l+b+b
                                  58 = 2l + 20
                            58-20 = 2l
                                   2l = 38
                                     l = $\frac{38}{2}$
                           length = 19 metres
