In this problem, we're given that the base is 10 inches
and the height is 5 inches.
Now, plugging into the formula, we have
.
Now, it doesn't matter which order we multiply.
So we can begin by multiplying (1/2) (10 in.) to get 5 inches.
Now, (5 in.) (5 in.) is 25 in².
So the area of the triangle is 25 in².
