Consider the origin as the point of right angle
So, (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- 14 years agoHelpfull: Yes(10) No(0)
- area of triangle=.5*8*12= 48
let the side of square is= x
so, x^2 + 0.5*x(8-x) + 0.5*x(12-x)=48
so, 4x-0.5x^2+x^2+6x-0.5x^2=48
10x=48
x=4.8
