Ineed how to do arrays and an expanded algorithm

Array:
1                                                   
1this is the Y axis
1
1
111111111111 this is the X axis
so there's a y axis and x axis.
You need to count how many dots AKA 1's are
on the x axis and y axis and multiply them.so in 
this case it would be 5 times 12 so the answer would be 60.
