Question

A garden is 140 m long and 90 m wide .It has an inside path of uniform width 3.5 all around it .Find the cost of watering the remaining portion at 60 paise per square meter?​

Answer 1

Answer:

Here we subtract 7m from both the length and breadth of the outer rectangle because it is given that the width of the path is 3.5m all around so in the length there will be reduction in both the sides similarly in breadth. Hence we subtract 3.5+3.5=7m from the length and breadth.
