Question

a rectangular park is 45m long and 30m wide.a path 2.5m wide is constructed outside the park.find the area of the path and the cost of constructing it at rs 125/m2

Answer 1

Length = 45m

Width = 30m

Area of this rectangle = 45 × 30 = 1350m$^{2}$

Increased length = 45 + 2.5 = 47.5m

Increased width = 30 + 2.5 = 32.5m

Area of larger rectangle = 47.5 × 32.5 = 1543.75m$^{2}$

Area of path = Area of large rectangle - Area of small rectangle

= 1543.75 - 1350 = 193.75m$^{2}$

Therefore, total cost = 193.75 × 125 = Rs. 24218.75

Hope this helps :)
