Answer:

The correct answer is B.  145 in²

Step-by-step explanation:

Let's recall that formula of the surface area of a pyramid:

S.A. = 1/2*(4 * side of the base * height) + side of the base ²

Replacing with the values provided, we have:

S.A. = 1/2*(4 * 5 * 12) + 5²

S.A. = 1/2 * 240 + 25

S.A. = 145 in²
