ABC is a right triangle
Area of right triangle = 1/2 × base × height
 
                                  = 1/2 × AB × AC
 
1/2 × (x) × (x+5) = 150

x(x+5) = 300

x² + 5x - 300 = 0

(x+20)(x-15) = 0

x = 15 

Sides AB = 15 cm and AC = 15 + 5 = 20 cm

Hypotenuse BC =  \sqrt{20^2 + 15^2}

                          =  \sqrt{400 + 225}

                          =  \sqrt{625}

                          =  25
