33,200 sq units (option A)

Step-by-step explanation:

Surface area of triangular prism = base × height + length ×perimeter of triangle

base = j = 150 units

height = h = 40 units

length = k = 85 units

m = 85 units

Perimeter of triangle = j + m + m

Perimeter of triangle = 150 + 85 + 85 = 320 units

Surface area of triangular prism = 150(40) + 85(320)

Surface area of triangular prism = 6000 + 27200

Surface area of triangular prism = 33,200 sq units (option A)
