Ok so total distance is 22 cm. And 2 sides r equal and third side is 6cm. So we can currently put this in the equation: 22=x+x+6 (x represents the two sides) they can be the same variable since they are equal too.
Steps for solving the equation: 22=2x+6
16=2x
x=8.
The two equal lengths of the triangle are 8 cm long.
