Ans 3:

Admin from SOF, Noida
Class : Class 10
Answer : D

Solution
Let the length of one side of the path (outer square) be x.
Area of lawn + path = x2
Length of one side of the lawn = (x -2)
Area of path = x2 - (x-2)2 = 40
Solving the above equation x = 11
Side of lawn = 11 - 2 = 9
Area of lawn = 81 m2

Chaitanya L K from SKCHEC, bangalore
Class : Class 8
Correct answer is 40 (area of path) 81(area of lawn)=121 sq mtrs. This option is not given

Ans 5:

Venneti Bhargav from gyan bharati, New Delhi

wrong answer because the question says to include area of pathway as well as are of lawn

Ans 6:

Ashwin Shridhar from Vidyashilp Academy, Bangalore

area of the lawn is 81 sq mtr but your question says including the path which will be 121 sq mtr. this option is not there. You need to remove including path from the question.
