what is the ratio for the surface areas of the rectangular prisms shown below given that they are similar and that the ratio of their edge lengths is 73 class=

Respuesta :

Answer:

D

Step-by-step explanation:

Given 2 similar figures with sides in the ratio a : b, then

ratio of areas = : a² : b²

Given that the ratio of the edges of the 2 similar prisms is

7 : 3, then

ratio of surface areas = 7² : 3² = 49 : 9 → D

Answer:

d
