Question

a 3 M wide path runs outside and around a rectangular Park of length 125 M and breadth 65 M find out the area of path also find out the cost of putting trials on the path @ rupees 56 per metre square​

Answer 1

Answer:

The area of path is 1176 m² and the cost of putting trials on the path is                     Rs. 65,856.

Step-by-step explanation:

Given that rectangular park have length = 125 m and breadth = 65 m

So, area of park = length × breadth

                           = 125 × 65

                           = 8125 m²

Now, it is given that 3 m wide path runs outside the park.

So, length of rectangle formed outside the park = 125 + (3 + 3) = 131 m

breadth of rectangle formed outside the park = 65 + (3 + 3) = 71 m

So, area of rectangle formed outside = length × breadth

                                                              = 131 × 71

                                                              = 9301 m²

So, the area of path = area of rectangle formed outside - area of park

                                 = 9301 - 8125

                                 = 1176 m²

So, the cost of putting trials on the path = 1176 × 56

                                                                  = Rs. 65,856
