Answer: Sides will be 10cm ,10cm ,6cm.
Explanation:
We have given that
In isosceles triangle ,
Let the base be x
Let the equal sides of isosceles triangle be x+4
Perimeter means the sum of boundary
∴ [tex]Perimeter= x+x+4+x+4= 26\\3x+8=26\\3x=26-8\\3x=18\\x=\frac{18}{3}\\x=6 cm[/tex]
So, the equal sides will be [tex]x+4=6+4=10cm[/tex]
and the base = 6cm.
