Question

a rectangular Park is 50 M long 36 metre broad a path 4 m broad is running outside the park along its boundary find the cost of a meeting this Park at the rate of 400 per 10 solution question

Answer 1

since, cost = area×rate
therefore,
first find area of park

area of rectangular park + area of 4m broad path

(50×36) + 2(4×36 + 4×50)
1830 + 688
2518m

now
rate is rs.400 for 10m
i.e, 40rs. for 1m

therefore
cost is area × rate
i.e, 2518 × 40

100720 is the ans.
