Question
A rectangular park is 120 m long and 104 m wide. A 1-m
wide path runs along the boundary of the park, remaining completely inside the park area. Thus, the outside edges of the path run along the boundary wall of the park. The inside edges of the path are marked with a white line of negligible thickness. If it costs ₹2.50 to mark each metre with the white line, then how much would it cost (in ₹) to fully mark the inside edges of the path?Solution
If we have to mark inside edges of the path that mean perimeter of rectangle having sides 118 m in length and 102 m in breadth Perimeter = 2(l×b) => 2(118+102) => 2 × 220 = 440 m => cost of 1 m is 2.5 Rs., then for 440 m => 440 × 2.5 = Rs. 1100
