The formula to find the area of a triangle is A=%281%2F2%29BH, where B is the length of the base and H is the height. So 60=+%281%2F2%2924H, and we can find that H=5. Using the altitude of the isosceles triangle and half of the base, we can apply the Pythagorean Theorem(a%5E2%2Bb%5E2=c%5E2) to find the length of the other two sides. So 12^2+5^2=144+25=169=13^2, and we get the length of the two sides are 13.
The perimeter of this triangle is then 24+13+13=50
