To find the perimeter, first find the length of the two equal sides using the Pythagorean theorem. Each side is the hypotenuse of a right triangle with one leg as half the base (10 units) and the other leg as the height (24 units). The hypotenuse is √(10^2 + 24^2) = √676 = 26 units. The perimeter is 20 + 26 + 26 = 72 units.
