Question

The length of side XY is ______.

  1. 3 cm
  2. 5 cm
  3. 8 cm
  4. 11 cm

hintHint:

Polygon is a two- dimensional closed figure which is consist of three or more-line segments. Each polygon has different properties. One of the polygons is quadrilateral. Quadrilateral is a four-sided polygon with four angles and the sum of all angles of a quadrilateral is 360 degree . Here, we have to find the measure of side XY in the given quadrilateral using the properties of the quadrilateral.

The correct answer is: 8 cm


    In the question there is a parallelogram WXYZ whose longer side measures 8 cm and shorter side measures 3 cm.
    Here, we have to find the measure of XY.
    Since, the opposite sides of a parallelogram are equal.
    text  So,  end text W Z equals X Y equals 8 space cm
    Thus, the measure of XY is 8 cm.
    Therefore, the correct option is c, i.e., 8 cm.

    Parallelogram is a four-sided polygon whose opposite sides are parallel and equal to each other and the opposite angles are equal to each other. The sum of all angles of a parallelogram is 360 degree    and sum of two consecutive angles is 180 degree . The diagonals of a parallelogram bisect each other and the angle into two equal halves. Here, we have to use these properties of a parallelogram and solve the given question.
