The length of the rectangle is 3 times the width. what would be the missing coordinates?

(3a, a)

(a, 3a)

(a, a)

(3, 0)

Answer : The coordinates will be, (3a, a)

Step-by-step explanation :

As we are given that:

In the diagram, x-axis represents the length of the rectangle and y-axis represents the width of the rectangle.

Length of the rectangle is 3 times the width. That means, the expression will be:

Let the length of the rectangle be, L and width be, W

L = 3 × W

In the given diagram:

Width (W)  = a  (from y-axis)

So,

Length, L = 3 × W

Length, L = 3 × a

Length, L = 3a

Therefore, the coordinates will be, (3a, a)
