3A) 0.8 to find this you'll need to find the square root of 0.64

3B) 1.1 is your answer because 1.1*1.1 is 1.21 find the square root of 1.21 and your answer will be 1.1

4A) find the square root of 0.3 which is ABOUT 0.55. Multiply 0.55 by itself and you will get over 0.3.

5) D^2= L^2+W^2

3.4^2= 11.56
