15*12=180 / 2= 90 then the answer is 90 m

You can not just multiply 12 and 15, because they have different unit of measure (cm and m, respectivley).
Then convert the m to cm before you multiply
Then convert the m to cm before you multiply then divide it by 2 or 3
Right, but you should have done that in your solution :-) Also, you did not identify what you solved for the benefit of the poster of the question. Triangular prism is a solid figure. You solved for the plane area (Triangle's area). Either, it's surface area or volume. Unless the enquirer identifies what is required of the problem, smart brainly users here are careful not to post their answers. :-) Have a nice day:-)
