If A is set of different triangles in the plane and B is set of all po – InterviewSolution

1.	If A is set of different triangles in the plane and B is set of all positive real numbers. A relation R is defined from set A to set B such that every element of set A is associated with some number in set B which is measure of area of triangle. Is this relation as function?
Answer» Two or more different triangles may have same area. But area of each triangle is unique. This means each element (triangle) of set A is associated with unique value (Area) of set B. So, given relation is function.
