Question
What is the measure of side AB?
- 14 cm
- 3 cm
- 8 cm
- 11 cm
Hint:
Assume the figure to be a parallelogram, as the observation infers so.
The correct answer is: 3 cm
3 cm
By closely observing the given figure, we can infer that the sides AB and CD are parallel to each other just like sides AD and BC. Hence, ABCD is a parallelogram.
Hence, we know that opposite sides are equal in length. Hence, the side opposite to AB is CD, which has a length of 3 cm. therefore, AB = 3 cm.
A parallelogram is a 2D polygon which has 2 sets of equal and parallel sides which are opposite to each other.

¶Perimeters: The scale factor and the perimeters' ratios are identical. The scale factor is the same for any ratio between two similar shapes (diagonals, medians, midsegments, altitudes, etc.).
Area: The area is the region defined by an object's shape. The area of an object shape is the space covered by a figure or any two-dimensional geometric shape in a plane. All shapes' areas are determined by their dimensions and properties. Different shapes have various areas.Area of Rectangle = a × b
