Question 308507
in an isosceles triangle, the third side is 50% of the length of one of the equal sides. Find the length of each side when the perimeter is 125ft. i know the answer i just dont know the equation?

let the length of the equal side be x

The other side will also be x

Thethird side = 1/2 x

x+x+x/2 = 125
2x+2x +x  / 2 = 125

5x/2 = 125

5x= 250
x=50  feet are the two sides
the third side = 25
