Kyle is planning to build a house. The following is a blueprint he drafted when starting the project.

Part A: If the scale of the drawing is 1 cm = 5 ft, find the perimeter of the scale blueprint in centimeters and find the perimeter of the actual house in feet.

Part B: Given that the actual perimeter of the house remains the same from Part A, choose a new scale for a different scale drawing of the same house. Then, find the perimeter of the drawing with the new scale.

1- is the product of two rational numbers irrational or rational? first, make a hypothesis by multiplying two rational numbers. then, use variables such as x=a/b and y=c/d and the closure property of integers to prove your hypothesis. 2- what do you think the product of a nonzero rational number and an irrational number is? is it rational or irrational? make use of variables, the closure property of integers, and possibly a proof by contradiction to prove your hypothesis. 3- why do we have to specify that the rational number must be nonzero when we determine what the product of a nonzero rational number and an irrational number is? if the rational number were 0, would it give us the same result we found in part b?
