Question 314813
The shortest side of an isosceles triangle is half the
length of each of the equal sides. The perimeter of
the triangle is 80 inches. What is the length of each
side?

..
Let the length of  be equal side be x inches
shortest side = x/2
Perimeter = x+x+x/2 = 80
LCM = 2
2x+2x+x /2= 80
5x = 160
x=160/5
=32 in
the equal sides will be 16 in.
