In a right angle triangle, length of perpendicular is 16 cm and length of hypotenuse is 20 cm. A square is inscribed in a triangle. One of the vertices of square coincides with the vertex of triangle. What is the maximum possible area of the square (in cm2)? |
\(\frac{1296}{49}\) \(\frac{2304}{49}\) \(\frac{2304}{64}\) \(\frac{4384}{49}\) |
\(\frac{2304}{49}\) |
Using pythagoras theorem BC = 12 cm ΔCXY ∼ ΔCBA \(\frac{CX}{CB}\) = \(\frac{XY}{BA}\) ⇒ \(\frac{12-a}{12}\) = \(\frac{a}{16}\) ⇒ 48 - 4a = 3a ⇒ 48 = 7a ⇒ a = \(\frac{48}{7}\) cm Now, Side of sqaure = \(\frac{P × B}{P + B}\) = \(\frac{16 × 12}{28}\) = \(\frac{48}{7}\) cm Area of square = \( {\left({\frac{48}{7}}\right)}^{2}\) = \(\frac{2304}{49}\) cm2 |
