I will mark brainliest!! if you help me :) Devon places a rectangle in the coordinate plane so that the lower left vertex is at the origin and the longer side of the rectangle is along the x-axis. Devon knows that the length of the rectangle is 4 times its width. He labels the coordinates of the upper left vertex as (0, a).

What coordinates should Devon use to label the upper right vertex of the rectangle?

A. (0, 4a)

B. (4a, 0)

C. (4a, a)

D. (a, 4a)

E. (4a, 4a)
