Hey buddy,
◆ Answer-
Area = 59 m^2
Cost = Rs. 4230
◆ Solution-
# Given-
s = 30 m
w = 1 m
# Solution-
Area of the whole park-
A1 = s^2
A1 = 30^2
A1 = 900 m^2
Area of the park without path-
A2 = (s-w)^2
A2 = (30-1)^2
A2 = 841 m^2
Area of the path
A = A1-A2
A = 900-841
A = 59 m^2
Cost of construction of path-
Total cost = 59 × 70
Total cost = 4130 Rs.
Thus total cost of path construction is Rs. 4130.
Hope that is helpful...

Answer:
Cost of construction of path = Rs. 8120
Step-by-step explanation:
Given Details are
Side of square park = 30 m
Width of path= 1 m
We can find the area of path of 1 m length as given below in a simple way
When 1 m wide path is constructed in the area then it would have two side of 30 m length and balance two side of (30-1-1)= 28 m
Total length of path of 1 m width is =30x2+28x2= 116 m
Area of path of 1 m width= 116 sqm
Now rate of construction of path per sqm is Rs. 70
Total cost of construction of path = Rate x area
= 116x70= Rs. 8120
