If i have a round rug in a square room which measures 100 square feet.
 how many square feet does rug cover? 
:
Find the side of the square room,
s = {{{sqrt(100)}}}
s = 10 ft
:
Assuming it just fits inside the room.
This will also be the diameter of the round rug; radius = 5 ft
A = {{{pi*5^2}}}
A = 75.54 sq/ft
