Step-by-step explanation:
x+x+26/2=71/2
2x=71/2-26/2
2x=45/2
x=45/2*2
x=45/4 cm
hope it helps you
please follow me
Base=26/2cm=13cm
Perimeter =71/2cm=35.5cm
In isosceles triangle,two sides are equal.
Let the two sides be x
Now,ATQ,
x+x+Base=35.5
2x+13=35.5
2x=35.5-13=22.5
x=22.5/2=11.25
The length of each equal side is 11.25cm
