Question

Find the area of the triangle

-
The answer [should be] 38.5 but I just can’t figure out how to get there…

Answer 1

Explanation:

the area of a triangle is always :

baseline × height / 2

the height is the line from the vertex opposite of the line we choose to be baseline to the baseline in a right (90°) angle.

and yes, that applies also to heights that actually land outside the triangle, like in this example.

so, the baseline here is 11, the height is 7.

the area is :

11 × 7 / 2 = 77/2 = 38.50
