first taking a part see there its written length of side of square and its perimeter so you can just keep a copy and pen in your hands just write length is 3 cm means length of side of square is 3 centimetre then find the perimeter then increase the length if you will increase by 1 cm then new length of square is 4 cm so its perimeter will also increase then take length 5 cm then its perimeter will again increase means when we are increasing the length of side, perimeter is also increasing side by side and directly related things are that which if one increase then other also increase........
let's take one example of inversely related let's take f part where its number of people and time taken to complete the work see you will see that if the number of people less then it will take lot of time to do a work and if number of people are more than they will take less time table easily complete that work in a few times but if the people are less than the time will increase and if the time is less means a people are more than the time is less so they are inversely related
