The length of the two equal sides of the isosceles triangle is 21 cm, and the length of the other side is 7 cm. This is because the perimeter of the triangle is 89 cm, meaning that the sum of the lengths of all three sides must equal 89 cm. Since the two equal sides are 7 cm longer than the other, the total length of the two equal sides is twice the length of the other side plus 14, which equals 21 cm. Therefore, each of the two equal sides has a length of 21 cm, and the remaining side has a length of 7 cm.
