Question

If the ratio of the corresponding side lengths of two similar polygons is 6:11, what is the ratio of their areas? A. 6:11 B. 12:11 C. 36:11 D. 36:121

Answer 1

The answer is D. because they are both the same ratio by squared-
6 squared is 36 and 11 squared is 121
So it's 6:11::36:121

Answer 2

D=36/121

you think about it, it makes sense why area would be the scale factor squared. Area involves two dimensions multiplied together. With scale factor, all you're really doing is multiplying the scale factor times itself.
