Question

a rectangular swimming pool is 15m long and 7m wide. a path 1m wide is constructed outside the swimming pool. find the area of path and the cost of constructing it at the rate of rs.50 per m.

Answer 1

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
