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.
