Question

Q1: A rectangular gassy plot is 112m long and 78m
broad. It has 2.5m wide gravel path all around it on the
inside . Find the area of the path & cost of
constructing it at Rs. 120 per meter square. ​

Answer 1

Step-by-step explanation:

length of plot = 112m

breadth of plot= 78m

width of path = 2.5 m

area of path = area of plot - area of plot exculing path

= 112*78 - (112-2*2.5)*(78-2*2.5)

= 8736 - 107*73

= 8736 - 7811

= 925 SQM

cost of construction

= 120*925

= 1,11,000
