Answer 2

Answer:

925 sq.cm.

Rs.4162.5

Step-by-step explanation:

Length of Grassy Plot = 112 m

Width of Grassy Plot = 78 m

We are given that t has a gravel path 2.5m wide all around it on the inside.

So, Length of Gravel Path = 112-(2.5+2.5)= 107 m

Width of Gravel Path = 78-(2.5+2.5)= 73 m

Area of Path = Outer area - Inner area  

             

             

Hence the area of the Path is 925 sq.cm.

Cost of constructing 1 sq.m. = rs.4.50

Cost of constructing 925 sq.m.=  

                                                 =  

Hence the total cost is Rs.4162.5

We Didn't add 5 to it instead of subtracting even though it is written all around it on it's side because it is written inside not outside
