Step-by-step explanation:

on the first one you can actually draw a number line and show a positive side and the negative side so you can actually decide the spacing like we can say the scale like one centimetre represents 4/4 like what I did.

On the second one you can actually choose to write any kind of situation that you prefer for instance, i chose Point Marks that you're given in an exam. If you didn't give the assignment on time then you get -5 then you gave the assignment on time you get +5 marks then sometimes you get zero marks like you fail the assignment you get zero then the zero always represents the neutral number like a marker that differentiates the integers from negative to positive and vice versa.

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6
