(B) 1:2
(C) 4:1
(D) 1:4
9. Sides of two similar triangles are in the ratio 4:9. Areas of these triangles are in the air
(A) 2:3
(B) 4:9
(C) 81:16
(D) 16:81
​

Answer 1

Answer:

8 C

9 D

Step-by-step explanation:

8C) 4:1

9D) If two triangles are similar to each other, then the ratio of the areas of these triangles will be equal to the square of the ratio of the corresponding sides of these triangles

(4/9)^2 = 16/81
