When we write a line equation in the form

m is the slope of the line, and q is the y-intercept.
Since we want the y-intercept to be -3, our line will look like

In order to fix the slope, remember that two parallel lines have the same slope. So, the slope of the given line y=2x-5 is 2, and since we want a line parallel to this line, our slope will be 2 as well.
Plugging the values, we can finish the equation:

Helloooo, Your answer for part A is 13 cm
You answer for part b is 2600
13 x 10 x 20 = 2600
A. 80
b.100
c.80
d.80
e.20
f. 120
These are all in degrees.
Hope this helps.
