Answer:
the area is 3040 m
and 40580rupees
Given :
- Width of path = 5m
- Rectangle formed by path + field has dimension = 200m × 60m
To find :
(i) Area of path
(ii) Cost of constructing path at ₹15/m²
Formula used :
- Area of rectangle = length × Breadth
Solution :
As path is around all side of field , then
- Length of rectangle formed by path and field = Length of field + (2×width of path)
➝ 200m = Length of field + (2×5m)
➝ Length of field = 200 - 10 m
➝ Length of field = 190m
_______________________________________________
Breadth of rectangle formed by path and field = Breadth of field + (2×width of path)
➝ 60m = Breadth of field + (2×5m)
➝ Breadth of field = 60 - 10 m
➝ Breadth of field = 50m
_______________________________________________
(i) Area of path = Area of rectangle formed by path and field - Area of field
➝ Area of path = (200×60) - (190×50) m²
➝ Area of path = 12000 - 9500 m²
➝ Area of path = 2500 m²
_______________________________________________
(ii) Cost of construction = Area of path × rate
➝ Cost of construction = 2500m² × ₹15/m²
➝ Cost of construction = ₹37500

ANSWER :
(i) Area of path = 2500 m²
(ii) Cost of construction of path = ₹37500
