The square root of 100 is 10. The drawing must be 10 cm by 10 cm.
1 cm = 2 ft, so 10 cm must equal 20 feet.
20 * 20 = 400 square feet

3/6+1/6+1 2/3
Make 1 2/3 into an improper fraction:
5/3
Give them all common denominators by multiplying both sides of 5/3 by 2:
10/6
Then the question becomes:
3/6+1/6+10/6
Now you add the numerators and the denominator stays the same:
14/6
Now you can simplify by dividing both sides by 2:
7/3
Now you can make it a mixed number:
2 1/3
Hope this helps :)
