Q2 of 99 Page 248

The rectangular land of Pritam has 5 meter wide path all around it on the outside. The length and width of the rectangular land are 2.5 dkm and 1.7 dkm respectively. Let us write by calculating that how much cost will be required for fencing around the outer side of path at the rate of Rs. 18 per in meter.

The length of rectangular land meter


The width of rectangular land meter



The distance covered to go one round along outer path ABCD = perimeter of rectangle



Where a = length and b = breadth


meter


meter


Cost required for fencing around the outer side of path = Perimeter × Rs. per meter



Hence, cost required for fencing around the outer side of path is Rs. 2,052.
