moments and force

sam makes a punch hole with the perforater( two holes ). She presses the lever at A down with a force of 40 N. Calculate the total force which a single pin presses on the paper.

2. Relevant data

3. The attempt at a solution
would it be :
40 N X 5 cm = 1,1cm X 'x' ?

we look for f such that

40*(5+1.1)=(2f)*1.1

thus f=... N.
