The area of the triangle is 78 units squared. Why? Well, the formula for calculating the area of a triangle is 1/2bh, which simply means to multiply base times height times 1/2. You could also multiply base times height then divide your answer by 2, because that’s the same thing as multiplying by 1/2.
Our base of the triangle: 13 units
Our height of the triangle: 12 units
Because the formula requires multiplying base times height, we can do 13 x 12. 13 x 12 = 156. However, we are not done. We now must multiply our answer (156) by 1/2 or divide it by 2. I would recommend to divide it by 2 because it is easier that way. 156 divided by 2 gives us 78. Therefore, by using the formula bh/2, we will find that our result is 78 units squared.
