Solution




Given

    • Two sides of a right-angled triangle.
      o One of the perpendicular sides, \(\frac{y}{2}\)
      o The hypotenuse = y
      o \(y^2\) = 2

To Find

    • Area of the triangle

Approach and Working Out

    • Ratio of one perpendicular side to the hypotenuse is \(\frac{y}{2}\): y
      o We can infer that the side ratio will be 1: √3: 2.
      o Sides are \(\frac{y}{2}\), \(\frac{√3y}{2}\), y
    • Area of the triangle,
      o ½ × \((y/2)\) × (\(\frac{√3y}{2}\))
      o √3\(y^2\)/8

      o (√3 × \(2^2\))/8

      o \(\frac{√3}{2}\)

Correct Answer: Option B
