Felicity is placing a rectangle in the coordinate plane. she iknows that the longer side of the rectangle is 3 times it’s shorter side. she places the longer side on the x-axis. what coordinates should she assign to the top-right vertex of the rectangle? enter your answer in the box

(3a, a)

Step-by-step explanation:

We are given that Felicity is placing a rectangle in the coordinate plane.

Assuming,

a to be the shorter side of the rectangle; and

b to be the longer side of the rectangle.

We know that,

Therefore, the dimensions of the rectangle will be .

So the final coordinates that Felicity should assign to the top-right vertex of the rectangle are (3a, a).

- 70

this is the answer for you hope it
