Answer:
Step-by-step explanation:
Outer rectangle measurements :
length = 15m + 1m + 1m = 17m
breadth = 7m + 1m+ 1m = 9m
inner rectangle measurements :
length = 15m
breadth = 7m
Area of path = Area of outer rectangle - Area of inner rectangle
= ( 17m x 9m) - ( 15m x 7m )
= (153 m²) - ( 105 m²)
= 48m²
Cost of construction of path = Rs. 50 per m²
then for 48 m² = Rs.48 x 50 = Rs.2400
