Answer: the square root of 3 is: (a number) times ITSELF is equal to 3. Therefore, if you multiply that number times that number again, it is equal to 3. 
Ex1- sqrt of 4 times the sqrt of 4 —> 2 times 2 which is 4
Ex2- sqrt of 9 times the sqrt of 9 —> 3 times 3 which is 9

Answer:
the area of the mat = total area added minus the original area of the water color painting.
length of the mat is: 
L = 21 in + 3 in + 3 in because 3 in  is added to each side
 L = 27 inwidth of the mat is:w = 11 in + 3 in + 3 inw = 17in
Area mat = (27 in x 17 in) - ( 21 in x 27 in)
area mat = 108 sq in is the area of the mat
