1.	1 metre broad pathway is to be constructed inside the boundary of a rectangular plot. The area of the plot is 114 sq. m. the cost of construction is Rs. 50 per sq. metre. Then find the total cost of production.1). Rs. 4,8002). Rs. 4,0003). Rs. 2,4004). Rs. 5,000
Answer» Let ‘l’,’B’ be the LENGTH and breadth of the rectangular plot as shown in the figure. Area of 1 metre BROAD pathway = Area of outer RECTANGLE – Area of inner rectangle ⇒ Area of 1 metre broad pathway = lb – (l – 2)(b – 2) ⇒ Area of 1 metre broad pathway = lb – lb + 2L + 2b – 4 Area of 1 metre broad pathway = 2(l + b) – 4 ? We don’t know the values of l and b, the given data is inadequate.

Answer»

Let ‘l’,’B’ be the LENGTH and breadth of the rectangular plot as shown in the figure.

Area of 1 metre BROAD pathway = Area of outer RECTANGLE – Area of inner rectangle

⇒ Area of 1 metre broad pathway = lb – (l – 2)(b – 2)

⇒ Area of 1 metre broad pathway = lb – lb + 2L + 2b – 4

Area of 1 metre broad pathway = 2(l + b) – 4

? We don’t know the values of l and b, the given data is inadequate.
