let the first square side be X, and
second be (X+5)

so

sum of area

x^2 + (X+5)^2 = 325

x^2 +x^2 +25 +10x = 325

2x^2 +10x = 325-25

2x^2 +10x -300 = 0

x^2 +5x -150 = 0

Now factorise

x^2 +15x -10x -150 =0

X (X+15) -10 ( X +15) =0

(X -10) (X+15) =0

X = 10, -15

X can not be negative
so

X = 10

side of small square = 10cm
side of bigger square =(X+5) = 15cm
