To find the area of a triangle, we can use the formula:

Now, we know the formula, let's do the math.
The base is 10 and the height is 17, so according to the formula, multiply the Base Ă— Height then divide by 2.
10 times 17 is 170. Remember to divide it by 2.
170 divided by 2 is 85.
Hence, your answer is 85 in.
