No not rational because you cant divide it
Start on -7 since it is the y intercept(b). 4/1 is the slope. So from seven you would go up 4 right 1.
Answer
h = 8.12 cm
Explanation
Area of a parallelogram = b • h
We know the area is 20.3 cm^2 and that the base is 2.5cm.
Therefore 20.3 cm^2 = 2.5h
20.3/2.5 = 8.12 cm
h = 8.12 cm
37 more than t would simply be defined as 
That's all!
