Question

a rectangle park is 50 m. and 35 m wide . a path is 2 m wide road outside the park. find the area of the path and cost of constructing it at the rate of rs.350/ per sq m

Answer 1

Area of rectangular park along with road
54×39
2106m2

Area of park except road
50×35
1750m2

Area of path=2106-1750
=356m2
cost of constructing= 356×350= 124600 rs

Answer 2

given,
length of park = 50 m
breadth of park = 35 m
area = (50 × 30) = 1500 square meter
length of park with path = 50+2 = 52
breadth of park with path = 35+2 = 37
area = (52×37) = 1924
area of path = (1924-1500) = 424
Hence the area of path is 424 sq m
Cost of constructing path = Rs ( 350×424) = 148400
hence the required cost is Rs 148400.
