(Add 25 to both sides)
( Take square of both sides)

If your asking for the length of the third side, to find it first we have to build an equation.
let's take x as the length of the two sides with the same length.
so your equation should be,
x+x+2x-7=44cm
=4x-7=44cm
+7 +7
=4x=51cm
÷4 ÷4
=x=12.75cm
length of the sides with equal length= 12.75cm
length of the 3rd side= 12.75×2-7=18.5cm
check,
12.75cm+12.75cm+18.5cm=44cm
hope this helps.....
