2024/039) The sides of a right angled triangle are in AP and area of 24. What are the length of sides

 Let the sides be a, a-d and a + d

we have (a-d)^2 + a^2 = (a-d)^2

or a^2-2ad + d^2 + a^2 = a^2 + 2ad + d^2

or a^2 -4ad=0

 or a(a-4d)=0

so a=4d

area of the \triangle  is \frac{a(a-d)}{2} = 24

or \frac{4d * 3d}{2} = 24

or d= 2 and hence sides are 6,8, 12
