Answer : A) square root
We know area of square having side 's' = s* s = 
For example
Area of square = 
To find side we take square root
Area = 
16 = 
Take square root on both sides

4= side
Betsy knows that the area of the rug is A square feet.

So answer is square root.
A) Scale of map is 1: 30,000
This is assuming that it meant 1 centimetre = 30,000 metres, for it gives no other information.
Multiply 1 with 30,000: 30,000 x `1 = 30,000
30,000 metres is your answer.
B) Scale is 1 inch: 6 miles. You are given 2.5 inches.
Remember that 1 inch = 6 miles.
Multiply 2.5 to both sides: (2.5) * 1 inch = (2.5) * 6 miles
2.5 inch = 2.5 * 6 miles
2.5 inch = 15 miles
15 miles is your answer.
