Hey hope it helps you
Step-by-step explanation:
First we need to find the perimeter of that rectangular field
Perimeter = 2(l+b)
=2(36+24)
=2(60)
=120m
The external paths width is 2.5m
Width is also called as breadth in this case.
As we know that the perimeter is 120cm, The length od the external path is 120 m
So here we need to find area cuz it has a width
Area of rectangle = l*b sq.unit
=120*2.5
=300 m^2
Coat of plotting = 4.5 per meter
Here we need to divide to find the construction cost
=300/4.5
= Rupees 66.66
Hope it helps you :)
