In this video, Anil Kumar explains how to find the sides of a right triangle when the area and hypotenuse are given. The problem involves a right triangle ABC with a hypotenuse of 10 cm and an area of 25 cm². The video demonstrates setting up equations using the Pythagorean theorem and area formula, solving these equations, and applying the quadratic formula to find the unknown sides. The solution reveals that the triangle is isosceles with both sides measuring 5√2 cm. The video concludes with a verification of the solution and encourages viewers to engage with the content.
