Step-by-step explanation:
Let the length of the base of an isosceles triangle be x cm.
Therefore, as per the given conditions,
Length of the congruent sides =2x−13 cm
Given, the perimeter of an isosceles triangle =24 cm.
Therefore, x+2x−13+2x−13=24
⇒5x−26=24
⇒5x=24+26
∴x=10
Base of a triangle =10 cm
Congruent sides =2x−13
=2×10−13=20−13=7 cm

Answer:
10cm, 7cm and 7cm
Step-by-step explanation:
Let the length of the base be x.
Then, One congruent lines is
2x–13
So, 2(2x–13)+x=24
= 5x–26=24
= 5x= 50
= x= 10
Length of base— 10cm
Congruent lines—7cm
