Hi fskilnik,

Even I like many others had marked option E, could you please explain how both statements together are sufficient to find the perimeter of the square?

GMATH practice question (Quant Class 17)

In the figure shown, the square ABCD is inscribed in the triangle EFG. What is the perimeter of the square?

(1) FG = 10
(2) The distance from E to the line FG is 6.

Source: https://gmath.net



\(? = 4x\,\,\,\,\,\,\, \Leftrightarrow \,\,\,\,\,\,\boxed{\,? = x\,}\)

Each statement alone is not sufficient, as proved by the geometric bifurcations presented in the figure above.

\(\left( {1 + 2} \right)\,\,\,\Delta EAB\,\, \cong \,\,\Delta EGF\,\,\,\,\,\,\,\, \Rightarrow \,\,\,\,\,\,{{6 - x} \over 6} = {{AB} \over {GF}} = {x \over {10}}\)

\(10\left( {6 - x} \right) = 6x\,\,\,\,\, \Rightarrow \,\,\,\,\,x\,\,\,{\rm{unique}}\)


The correct answer is therefore (C).


We follow the notations and rationale taught in the GMATH method.

Regards,
Fabio.
