Question 968436
Here's the way that I would do it:
First find what a square foot would be in square inches
{{{ 12*12 = 144 }}} sq in = {{{ 1 }}} sq ft
------------------------------------
Now look at what you want to do in terms of units only:
[ square inches ] / [ square inches / square foot ] = [ square feet ]
-------------------------------------
Then plug in numbers:
{{{ ( 43*10 ) / 144   = 430 / 144 }}}
{{{ ( 20*20 ) / 144 = 400 / 144 }}}
------------------------------
You can do the divisions
