Answer 2

Answer:

1:1

Step-by-step explanation:

We can let the base of the unshaded triangle = the length of rectangle = n.

We can let the height of the unshaded triangle = width of the rectangle = h.

The area of the unshaded region is the area of the unshaded triangle, which is:

1/2 x n x h = nh/2

The area of the shaded region is the difference between the area of the rectangle and the area of the unshaded triangle:

nh - nh/2 = 2nh/2 - nh/2 = nh/2

So the ratio is 1 : 1
