let the sides be x and (x+2)
Area of right angled triangle = height ×base/2
24*2 = x ×(x+2)
x = -8 Or x = 6 [zero product rule]
x = 6 [taking positive value]
Now,
sides are
6 and (6+2) = 8
Now,
By pythagoras theorem,
36 + 64 = hypotenuse^2
100 =
10 = hypotenuse
Now,
perimeter = 6+8 + 10
Perimeter = 24 cm
i hope this will help you
