The triangle is a scalene and achte triangle simce the sides are not the same length and the angles are less than ninety degree.
So there is 75 boxes of 12 right? You would figure out how much sticks you have by multiplying then you have to give them to 23 teachers. You take the total of sticks and divide among each teacher
I hope this helps :)
The correct answer is 60cm^2 because the area of a triangle is half base*height -> 30/2*40
