Answer:
C) A rhombus has four side that are the same length.
Step-by-step explanation:
Given:
A rectangle has a length of 20 cm and a width of 15 cm.
Length = 20 cm
Width = 15 cm
We need to explain why the rectangle is NOT a rhombus.
Now according to properties of Rhombus which are given below;
⇒All sides have equal length
⇒Opposite sides are parallel, and opposite angles are equal (it is a Parallelogram).
⇒The altitude is the distance at right angles to two sides
⇒And the diagonals of a rhombus bisect each other at right angles.
Since size of rectangle are length is 20 cm and width is 15 cm hence it is not a rhombus as Rhombus have all sides equal.
Hence Option C) A rhombus has four side that are the same length.
