consider the origin as the point of right angle thus (8,0)and (0,12) are the 2 vertices. equation of hypotenuse : 8y+12x=96.
now solve this with y=x(the diagonal of the largest square)
x=4.8, y=4.8 .
hence the answer

area of triangle is 1/2 * 12 * 8 = 48
side of square = x
the entire triangle split into two right angled triangle and one square with dimensions as follows
i) square with side x
ii) Right angled triangle with perpendicular sides x and 12-x
iii) Right angled triangle with perpendicular sides 8-x and x

sum of area of all three = 48
x^2 + 1/2*x*(12-x) + 1/2*x*(8-x) = 48
x = 4.8 cm

Ans
(B) 4.8 cm

b)4.8cm
by similar triangles, if the length of the square is x cm,
((12-x)/12)=(x/8)
i.e.,x=4.8cm

ans = 4cm
because the one corner of the square should lie at the mid point of the hypotenuous of right angled triangle. and the perpendicular distance from the mid point to any of the two opposite sides is 4cm and if we move that point up or down further then it will form a rectangle. hence largest possible square is of 4cm side.
