Answer:
Let the side of  one square be x.    Area = x*x = x²
Then the side of other square  would be 2x ,   Area = 2x*2x = 4x²
Combined area = x² + 4x²  = 5x²
This combined area = 45 cm²
you simplify 
Therefore  5x²  = 45   Divide both sides by 5
                  x²  =  45/5
                  x²  = 9        Take square root of both sides
                  x   =  √9
                  x  = 3
Length of larger square is 2x  = 2*3 = 6 cm
Length of larger square = 6cm
