Question 466977
The Perimeter of an isosceles triangle is 36cm. The total length of the two equal legs is 12 more then one-half the length of the base. find the lengths of three sides.
---------------------------
Let the base be "x".
Total length of 2 equal sides is (x/2)+12
---
Perimeter = x + (x/2)+12 = 36
---
(3/2)x + 12 = 36
(3/2)x = 24
x = (2/3)24 = 16
Then (x/2)+12 = 20 cm
So each of the equal sides is 10cm
========================
base = 16 cm 
Each equal side = 10 cm
