If the dimensions of a solid proportionally increase by a scale factor of 5/2, by what factor does the surface area increase?

A. 5/2

B. 5/4

C. 25/2

D. 25/4

Respuesta :

Answer:

D

Step-by-step explanation:

Given that the dimensions of  a solid are in proportion a : b, then

then the ratio of the area is a² : b²

Thus

scale factor = [tex]\frac{5}{2}[/tex] , then

area factor = [tex]\frac{5^2}{2^2}[/tex] = [tex]\frac{25}{4}[/tex] → D

Answer:

D
