Discrete math problem! Prove or disprove the following statement: “If two rectangles have the same area and the same perimeter, then they have the same dimensions (length, width).” Note that finding a pair of rectangles that meet the criteria and showing that their dimensions are the same is an example, not a proof. If you feel that the statement is false, then demonstrate it by showing that it leads to a contradiction, or by finding a counterexample.

Ex 2. Prove by contradiction the following claims. In each proof highlight what is the contradiction (i.e. identify the proposition Q such that you have Q ∧ (∼Q)). Claim 1: The sum of a rational number and an irrational number is irrational. (Recall that x is said to be a rational number if there exist integers a and b, with b 6= 0 such that x = a b ). Claim 2: There is no smallest rational number strictly greater...
