1) 

Let one side is x cm

Then other side is (x+5) cm

x^2 + (x+5)^2 = (25)^2

x^2 + x^2 +10x + 25 = 625

2x^2 + 10x - 600 = 0

x^2 + 5x - 300 = 0

x^2 + 20x - 15x - 300 = 0

x(x+20) - 15(x+20) = 0

(x+20) (x-15) = 0

x = -20 x = 15

Side cannot be negative

So, therefore one side is 15cm

other side is (x+5) = (15+5) = 20cm

2) Your question is not clear. Kindly provide the figure or the details about points P and Q.
