The weight seems like most accurate to me, even thought you didn't show me what type of measurement he took.
we are given

we can also write it as

now, we can use factor formula

we can use above formula
we get

now, we can simplify it

now, we can set it to 0

and then we can solve for x




now, we can use quadratic formula

now, we can plug values
and we get


So, we will get solution as
