Answer:

A.

Lateral area (LA) = 324 cm²

Surface area = 432 cm²

Explanation:

✔️Lateral area of the triangular prism = perimeter of the base (P) × height of prism (L)

Perimeter (P) = 9 + 12 + 15

Perimeter (P) = 36 cm

height of prism (L) = 9 cm

Lateral area (LA) = 36 × 9 = 324 cm²

✔️Surface area = bh + LA

b = 9 cm

h = 12 cm

LA = 324 cm²

Surface area = 9*12 + 324

= 108 + 324

Surface area = 432 cm²
