Combine these radicals. 3 square root of 2 -5 square root of 2

You can see that both terms involve the square root of two. Think of it as a variable, say x. Your expression becomes

area = length x width

length = 2 x width

32 = 2 x width x width

32 = 2 x width^2

36 = width ^2  

width = 6

length = 12

area is 32

perimeter = 2 x 12 + 2 x 6 = 24 + 12 = 36
