Find the area of the image below:

So for this, you will be splitting up this image into 3 triangles, find their individual areas, and then add those areas up. For this, make line IL and JL. And also remember that the area of a triangle is A = 1/2bh

Starting with triangle JKL, by counting its height is 3 and its base is 5. Apply those to the equation and solve:

Next with Triangle JIL, its height is 3 and its base is 5.

Lastly, we have Triangle HIL, its base and height are 5. Apply to the equation and solve:

Now that we have all the individual areas, we can add them up:

In short, the area of this image is 27.5 un^2.
