Well, first the formula is this:
\(A=bh\)
b=base
h=height
Translation: Area is base times height
So: 16×16=256
The area of the board is 256 inches\(^{2}\).
The small squares should each be only one inch on each side:
So:1×1=1
The area of each tiny square on the board is 1 inch \(^{2}\).
Hope this helps!
