Question

In the envelope ACDB, if  AD = 7 cm, then find the length of diagonal BC.

  1. 7 cm
  2. 3.5 cm
  3. 14 cm
  4. 28 cm

hintHint:

properties of rectangle
opposite sides are parallel and equal to each other.
Each interior angle is equal to 90 degrees.
The sum of all the interior angles is equal to 360 degrees.
diagonals bisect each other.
Both the diagonals have the same length.

The correct answer is: 7 cm


    here ABCD is a rectangle,
    and we know that The diagonals of a rectangle are equal.
    So, AD = BC = 7 cm  is the answer
