Let the length of smaller side be x cm
Then length of larger side=(x+5)cm
Given length of hypotenuse=25cm
we know that in right angle triangle(hypotenuse)2=(side)2+(side)2
So,x2+(x+5)2=()2
x2+x2+10x+25=
2x2+10x-=0
x2+5x-=0
Value of x from the above equation wil give the possible value of length of side of the given right angled triangle
