Question 978764
Each square is 
{{{(120*105)/126=100}}}{{{ft^2}}}
So each side is 
{{{S=sqrt(100)=10}}}{{{ft}}}
So you will have 
{{{120/10=12}}} squares across to make the 120 feet
and then you'll have 10 squares down to make 100 feet.
You'll have to break the remaining 6 squares in half to make the 5 feet.
By breaking them in half you'll then have 12 half-squares to go across the 120 feet. 
So {{{12}}}X{{{10&1/2}}} squares.
