Answer 1

1st of all pencil heel Is old Faison

as we know P = F/A

now pressure of girl pencil heel which are old Faison btw = 50/1 = 50 N/cm²

now pressure of elephants foot = 200/250 = .8 N/cm²

clearly 50>>.8 [ if you don't know this idk why are you here ]

so we learned today that don't weare pencil heel coz they are old Faison
