33,200 sq units (option A)
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)
