what's to explain? Write the facts in symbols:

p^2 + (p+5)^2 = 625

Now just solve for p and find p+5

Sum of squares

= p²+(p+5)²

=625

Expand

p²+p²+10p+25=625

2p²+10p=600

p²+5p-300=0

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

p=15 or p=-20, reject negative root

The sides of the squares are therefore:

p=15

p+5=15+5=20
