Answer:

Area = B x H + L (sum of sides of triangle)

= 9 x 12 + 10 (12 + 15 + 9)

= 108 + 360

= $468in^2$

Either your options are wrong or question is to find lateral surface.

Lateral Surface area = ( a + b + c) x H , where a, b , c are sides of the triangle.

Lateral Surface Area = (12 + 15 + 9) x 10

= $360in^2$

4/10 / 1/25 = 4/10 x 25/1 = 100/10 = 10.

10 can also be written as 10:1, so A is correct.
